My server has been kernel panicking on and off irreguarly every 2 days or so since I upgraded to cPanel 11, I'm not entirely sure whether this was the cause however I've isolated the fact it is a kernel issue. I am running CentOS 4.5 and was running Kernel "2.6.9-42.0.8.ELsmp" however switched to the kernel I was running before (2.6.9-42.0.3.ELsmp) and the same issue is still cropping up.
I thought that it may be a memory addressing issue or the like, however from looking up the issue, several C programming forums seem to suggest dodgy applications, the memory usage on the server does always seem fairly low and loads are generally healthy so this would seem to be supported.
The logs before the server kernel panics are as so:

I have an apache 2.2 server that is having issues handling a SSL request from a Virtual IP. The Virtual IP sends all requests via SSL to a particular port for which I have and is listening. It looks like my apache server (17.16.3.7) is trying to use HTTP to talk to the HTTPS request coming in from the virtual IP address. The ssl_startup_log Error below is when I try do https request to my-virtual-ip-address.com I don't have any issues using [URL]...how to troubleshoot this?

My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively. - the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11 - the external ip addresses resolve to the above internal addresses - the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?
Past shared hosting deals we been trying out sucks. We are a community forum that just started but know we will grow a big database in the future. We want to prepare now and have no problems. It's a LOCAL Radio-Control (R/C) forum.
What VPS Host would you guys recommend that handles forums well? So far, I broke down to WiredTree.com.
I am currently researching the options open to me for Virtualisation, the two main ones I have seen are Xen or KVM.
I mainly use CentOS (RHEL), but have read that the version of Xen with it is very old, broken and unstable. KVM isn't included in the kernel that ships with CentOS, as it is too old, apparently it was first featured in Kernel v2.6.20. There isn't likely to be an update till RHEL6, which is due for release first quarter of 2010. I can't wait over a year, so need to find another Distro for use as the Host OS/Hypervisor.
I have built a pretty powerful server, it has an Intel Xeon 3230 which has VT - so I might be better off using KVM over Xen. I am going to collocate this server, so realistically I can make this decision only once - as it would be a PITA to re-install a host Linux distro remotely.
I did a search on distrowatch for distros with the latest version of the kernel, and Slackware came up as being just one minor version behind the most current (v2.6.27.7).
Now this distro is very mature, so should be a fairly safe bet, but it is a 32bit version and can't host 64bit VMs. I have 8GB of ram so want to be able to use it all, and offer the choice of 32/64bit VMs. So that's that out of the window.
I have used Arch Linux on and off for a couple of years as a workstation OS, but because it is so bleeding edge, when pacman updates it can break itself. But I suppose if I just use it as the Host OS, and never let it update/reboot, then it won't break. It should be fairly lightweight and stable, as I will be installing the bare minimum packages. I have a management card, so if the server fails to boot, then I can still remote in to fix it.
If I do want to update the kernel, is it possible to update without rebooting? I think it is somehow... unless I can just reboot during an unused time at 3am or something.
As you can tell I am leaning towards KVM on Arch Linux (x86_64). Is this a good plan?
I've started looking into KVM to possibly to run alongside or even to end up replacing our current Xen infrastructure. The fact that it's built into the mainstream linux kernel is very appealing.
Are there any Control panels/basic frontends for this at the moment to allow users to Reboot/Reimage their VM's? At the moment its looking as though we would need something inhouse or custom developed
I installed FastCGI and configured it via fcgiconfig.js using this command
cscript fcgiconfig.js -add -section:"PHP" -extension:php -path:"C:PHPphp-cgi.exe" It configured fcgiext.ini and added the .php extension to the sites and what not.
When accessing a php script, I get the following error though:
FastCGI Error
The FastCGI Handler was unable to process the request. Error Details:The FastCGI process exited unexpectedly Error Number: -2147467259 (0x80004005). Error Description: Unspecified error HTTP Error 500 - Server Error. Internet Information Services (IIS) I did not do anything special with the PHP. It is the zip 5.2.5 from the site. I configured php.ini and move it to c:/windows. I granted IUSR permission on php-cgi.exe
I am trying to setup a subdomain and/or virtual host to redirect to a specific port and path. I am, however, having great difficulties doing this.
I have setup my server with DDYNS through my domain name registar.
Through the ddyns client I have set it to assign a subdomain of "outside.name.com" so that my server will have a easy name to get to instead of a dynamic ip address.
I have also setup on my registrars host records another subdomain of "inside.name.com" with a static IP address for internet network accessing to my server.
My problem is that I have a service/program on my server that I need access to both internally and externally and this service can only be access through a port of 32400 and HTTP address of /web. (e.g. outside.name.com:32400/web or inside.name.com:32400/web)
This is annoying for others to type out and I am just wanting to make it look pretty. Is there a way that I can create a VirtualHost or Subdomain of "service.*.name.com" that redirects them to ":32400/web" of the hostname they're on? (e.g. service.outside.name.com automatically forwards or proxies--to keep it pretty--to service.outside.name.com:32400/web)
I'm attempting to run PPA on Azure but I only have one IP to work with, the public IP address. It's not possible to communicate between servers using the internal IP addresses as they are not necessarily on the same sub net. How can I get PPA and service nodes running on a single IP address per machine?
An example of the error I get when setting up a service node is
Failed to execute command 'cscript /Nologo http_download.js http://<private ip address>/tarballs/Win32Bin/support.cab'. Check logs in 'c:POA_Deploy' at host '<public ip address>' for more details about the reasons of failure.
Is there a way to page results from ls through FTP similar to the way you can in your shell by using ls | less (or ls -l | more)? When I try ls | less through FTP, even on a linux server, it wants to output to a local file?
I have a Windows server running x32 2003 standard, and upgrading to x64 isn't possible right now because of software compatibility. We already have 4GB ram installed, but that is constantly maxed out. I was thinking about investing in a top-end SSD (Like the intel extreme), and use it as a dedicated disk for the paging file. I know its not quite the same as increasing memory, but I figure it will minimize the effect of the server always swapping memory contents in and out of the paging file.
Also, if you think this is a good idea, what SSD would you recommend? I'm thinking anything 16GB or higher is fine. I've heard good things about the Intel SLC, and Mtron.
to have certain administrative software products page an administrator under certain scenarios, such as failure of a hardware component? I've read about this functionality being possible in several scenarios, but am unsure of what is needed for it.
Similar to the concept of paging an administrator is sending a text message, which I'm also not sure about.
What is needed from a software, hardware, OS, etc perspective to get such functionality in your system?
I have a server setup and running shared hosting perfectly. I duplicated one of the plans and just set it to DEDICATED IP. This is for users that will be requiring SSL.
I then went into my panel settings and added in all the additional ip's. It even says in the panel listing "6 dedicated ip's available".
Yet, when I try to re-run the task for provisioning it constantly fails with the message:
Unable to create hosting. Ip address does not exist in client's pool ....
What setup would be right (as far as paging file goes) for running game servers on a dedicated box.
Specs core2duo 2ghz 2 GB RAM 300Gb HD Windows Server 2003 Standard
Right now it says it has 1512 MB allocated for the paging file. Just seems to me that programs would run better with a smaller paging file.
This is my first Windows server i have always used unix for a dedicated box so i dont have a clue how these settings such as page file affects a server.
We are trying to use a configure settings for an external SMTP server within Plesk (Windows 2008 R2 Plesk 12) but are receiving the following error message:
Error: Unable to encode IDN email address 'username': email address is invalid
We are trying to use a username for SMTP authentication as we do not have the option of using an email address with our current SMTP relay provider.
Is there any way around this so that we can use a username rather than an email address?
we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.
syslog shows that just before crashing, these entries were made:
kernel: kernel BUG at mm/rmap.c:479 kernel: invalid operand:0000 [#1]
dmesg also shows this:
... Brought up 2 CPUs zapping low mappings. checking if image is initramfs... it is Freeing initrd memory: 482k freed NET: Registered protocol family 16 PCI: PCI BIOS revision 2.10 entry at 0xf9f20, last bus=1 PCI: Using configuration type 1 mtrr: v2.0 (20020519) mtrr: your CPUs had inconsistent fixed MTRR settings mtrr: probably your BIOS does not setup all CPUs. mtrr: corrected configuration. ...
i've googled these messages and they point to ram problems.
hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.
they said this is a result of a sys configuration problem made by us.
Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.
I've only ever had a shared hosting account with Hostgator, plus a few freebie hosts. However, I'm now pulling some heavy traffic and I'm concerned that Hostgator is going to suspend me soon.
My traffic on Saturday for example was ~2600 unique visitors and ~5000 page views. All of this traffic was from WordPress blogs and a small SMF forum. I've since converted one of the blogs to a static site to limit my CPU usage and I've setup caching for my other WordPress blogs. Advice I've heard on the Hostgator forums is that 7000 page views per day for a database driven site is around the time you should be upgrading and based on my traffic from Saturday (which admittedly was a bit of a spike) I could potentially be receiving 150,000 page views/month, so about 20x the point at which they recommend upgrading at.
Anyhows, in a nutshell I need to upgrade, or risk Hostgator throwing a tantrum at me ... but I don't have a lot of cash to pay for an upgrade Due to my lack of cashflow I've been considering moving to a VPS. The company which has interested me the most is HostV.com who offer a 256 MB (with 1000 MB 'burst' RAM) for only US$39.99 which seems quite reasonable to me.
They say that their 256 MB plan should be able to handle over 5000 page views per day for a WordPress run site, but I'm a little suspect. Do any of you know if this is a reasonable expectation from a 256 MB chunk of a virtual server? I have no idea and am always wary of believing the sales pitch of a random company across the other side of the world.
PHPAuction GPL Enhanced V2.51 Auction Software seems to be the perfect solution for my client, but the PHP requirements are very specific and the host we currently are using doesn't allow anyone to play with .htacess which is the usual workaround. Can anyone recommend a host that they know has the following setup?
Minimal server requirements are as follows: - Apache web server - PHP 4.0.6 or later (see below) with safe_mode=Off - register_globals=on - no open_basedir restriction - MySQL Database - 3.0 or higher - "Cookies" MUST be enabled on your computer!
Alternatively, does anyone know of any auction software that restricts sellers to only the admin?
I have a client that asked me to educate myself about web hosting and make a recommendation to him about where he should be. He currently has a shared hosting server at Network Solutions and finds unexplained slow downs and disk corruption reports in his forums DB unacceptable.
I'm glad I found this site-lots of good info but nothing like throwing up some stats and seeing what people recommend. The client told me he wanted to move to a dedicated server but I'm thinking a VPS might do the trick. Especially if upgraded with dedicated Core as well as RAM such as wiredtree is offering.
Looking for a managed, Unix based server that in a typical month serves 100k unique visitors 230k page views 500Gb of downloads
But needs to be easily upgradeable to handle his expected traffic levels in the next year of monthly visits in the order of: 250k unique visitors 600k page views 1.1Tb of throughput As far as features:
*Currently they use about 15 gigs of disk space. Some of that is inefficient disk management but the bulk is them supporting previous software releases.
*needs to be fully managed
*US datacenter with all the features you guys would expect to have as far as backbone access, security, power backups, etc..
*Backups by provider. Let's say 5 gigs worth since the old software versions don't really need to be backed up.(I'll recommend his own backups as well)
*Either plesk or cpanel
*15 minute hardware SLA is what the client is asking for but i'd like to present some comparisons to 1 hour SLA companies to see how much he'd save.
And finally, i tried to search for the answer to this but the keywords kept bringing up lots of hits without good info. The client sells software so the bandwidth needed is pretty consistent until they release a new version. Then it skyrockets to the point they may have 1500 people trying to download a 50Meg file simultaneously. What is the right way to handle that? Use a CDN or negotiate with the hosting provider to provide burstable bandwidth as needed. As a side note while looking at many offerings I was most surprised that bandwidth seems to sold in large chunks with overage costs hidden.
I'm not quite sure how much of Ram I need for my vps, But I'm going to get 1GB Vps from wiredtree.com
Anyone can tell me what kind of website I would be able to run on such an VPS? If it's just wordpress driven website...
Maybe anyone can share how much traffic your site have and how much ram it's using?
At the moment I have website with about 40k uniques/day and ~100k pageloads per day hosted on shared hosting but they have gave me 3days to find another hosting because they say I use to much of their traffic...
