I've been plagued over the past few weeks when I noticed the server keeps rebooting randomly ...
I have a customer who is hosting a website on a dedicated server. The server is a high spec server with Intel Core 2 DUO E8400 processor, 4 GB DDR2 ECC RAM and a SATA Hard Drive. He is running only a single website which has a data entry section. The problem is that a few scripts when run consume 99% of the CPU. In fact, there is a particular script which even if run alone consumes 99% CPU. The code retrieves some records from the database by running an SQL query. The code is never executed. I have checked the sql query in the code and it runs fine if executed in SQL Query Analyzer. I know the problem is somewhere in the code, but cannot find the exact cause. Is there a tool to debug the asp code and find out may be the issue with the code? I have tried the Debug Diagnostics utility,

What happens is that sometimes, PHP script requests do not seem to terminate(?), but I do neither know why, nor do I know what is happening. It probably has something to do with scripts that process kind of a larger
how ya all debug email scripts that you create on a shared host when you don't have access to the sendmail/qmail/etc log files?
For example I have created two scripts. One uses the SwiftMailer PHP class and the other uses the PEAR class. The SwiftMailer one works just fine. The PEAR one does not and I have no clue as to why not.
My web hoster has graciously offered to let me look at the log file (I think) but that's only a temporary solution to the long term problem of debugging other email related scripts I might write in the future. Not to mention that I can't rely on every hoster allowing me to view such a thing (should I ever switch hosting companies).
Shared hosting is just fine for me at this point so switching to VPS or other hosting solutions is not neccessary (I'll just use the SwiftMailer class if it's the only one that will work but, it would be nice to know why the PEAR or other scripts may not work).
I had to reboot my server and about 20 minutes later I tried to access the web site but the page was not found... I am able to login to SSH. However, I am not familiar with *nix or the workings of CPanel... What should I do to get the sites back online?

Server went down last night, submitted a reboot request and now the server is not responding to SSH.
It does respond to ping, so I'm assuming Linux might have booted up OK
Has anyone experience with this type of issue?
I ordered a leaseweb express server 4 box with windows server 2003 and have been running it, installed some software etc which worked out fine.
Anyways, I wanted to disable tcp/ip filtering which I did and afterwards it prompted me that I would have to reboot the server for the changes to take place, I clicked ok and it rebooted. Now I just can't connect with remote desktop, I tried everything.
I'm guessing it either shut down or didn't reboot properly? I tried sending an email to leaseweb support 2 days ago but still no shadow of any reply..
It says that I can reboot the server using the SSC but when I log in there, I can't really find any reboot option.
How can I see the logs for my server before doing reboot to see why was high load in my server?
View 2 Replies View Relatedmy datacenter says that they have not had power failures(lol yeh right) but i cant seem to figure out why my server seems to be rebooting randomly. so far its happened early 3-5am my times today and yesterday, just its happened 4x more times this morning.
im not sure if cpanel is sending me bind start failures because its not set to auto start up on reboot or if it might be related... but the server seems fine.
anyway to auto reboot server every 6 hours?
will this effect on the server?
i'm running on CentOS 5 and whm
i have a dedicated server at theplanet.I dont have a remote reboot option.
a friend of mine said,that all dedicated servers have remote reboot options.he says that since i dont have a remote reboot option,i am probably on a shared server.is that correct.does theplanet have shared or vps offerings in the first place ?
i cannot reboot the server,but i can log in through shell as root type in shutdown - and turn the damn thing off.....
I have Plesk 8 installed I would like to create Scheduled Task as root to reboot the server in every 8 hours.
View 7 Replies View Relatedproblem I was having which was Windows Small Business Server 2003 would hang on boot up. I never got the time to reinstall the server until now.
I have installed the server and applied all updates. This worked fine until I install the Windows Server 2003 Service Pack 1 or 2. When I install SP1 or SP2 on reboot the server loads the Dell splash screen then the monitor LED light goes orange then green then orange and then just hangs with a blank screen.
I can boot into Safe Mode and uninstall the Service Pack and I can then reboot without any problems. I have installed ADAM SP1.
I have a cpanel, centos server that had to be rebooted due to the high load spike. I was unable to ssh in nor enter whm prior to the reboot so my only option was of course to reboot the server.
Now, I'm trying to trace the cause of the spike. RTG graphs show no indication of a ddos attack.
Inside whm, CPU/Memory/MySQL Usage shows no reds nor yellow warnings either except red for gzip (backup process) at 19% CPU. I doubt this is the cause.
This is from /var/log/messages of the logs slightly before and after the reboot.
Code:
Apr 9 13:31:49 server pure-ftpd: (?@70.250.201.162) [INFO] Logout.
Apr 9 13:32:05 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3
Apr 9 13:32:28 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3 .......
I have a problem with the server time, when I reboted the server, the time change 4 hours back. Only the time changed not the time zone.
To solve this, I have to sync the time from WHM and then it get the correct time.
at getting PDUs for the new facility where we plan to move our servers to. Our cabinet will have 2*20a circuits, so we're thinking of getting 2 APC PDUs (1 per circuit). Some offer remote reboot capability.
Our servers (Dell PowerEdge) have dual power supplies, and I assume the best thing is to plug one power supply into each circuit, so things stay up even if a circuit fails.
So, how would this work if we want to reboot? The servers can run on only one power supply, so does that mean we have to click reboot on the web interface of each PDU at exactly the same time?
I've never worked with PDUs before.. just cheap power strips and a call to the datacenter
Everytime i rebooted my server, my FTPd is always down and it won't start unless i restart my FTPd via WHM (CPanel server)
Sometimes, named failed too.
When I reboot my centOS 6.5 + Plesk 11.5 server, Nginx doesn't start and every time I need to go to Server > IP Addresses and click Reread IP.Then Plesk says that need to repair one of these ips, I click repair and then Nginx can start. ( I have 3 ips [2 ipv4 and 1 ipv6] )
View 3 Replies View RelatedI have a VPS (ConetOS 4.4, OpenVZ), it all works fine, however on reboot, the resolv.conf gets reset to some nameservers that are no longer in use, How do I change this so after a reboot it uses the nameservers I am using now?
My current resolv.conf looks like this:
nameserver 85.234.133.209
nameserver 85.234.144.209
We are facing this weird problem from the past few days. Whenever we reboot the Windows 2003 Service, the server becomes inaccessible from the network or the internet after reboot. It is only after we run the sharedaccess.reg file available from http://windowsxp.mvps.org/reg/sharedaccess.reg and reboot the server, we can access the server remotely. But the same thing happens after rebooting the server again. We are also not able to start the Windows Firewall service. We get an error while trying to start the Windows Firewall Service. The screenshot of the error message is attached with this post.

View 2 Replies View RelatedI have a problem with my plesk panel. Ever since I rebooted my server it won't load the IP:8443 page at all.
View 5 Replies View RelatedTwo month ago I installed plesk 11.5 on my server (with centos 6 or 7 I don't remember) Then i added my domain.com by clicking on "Add New Domain" and using the auto dns system configuration. All worked great. During this period, Parallels Plesk was auto updating to 12.x 1 week ago, I restarted my server, and my website was down (I think because DNS problem with 12.x or ip problem or port closed...)
So I formatted my dedicated server, then I reinstall Parallels Plesk 11 (with centos 6) and the website worked great. Then I re-formatted my dedicated server, then I installed Parallels Plesk 12 (with centos 7) and the website did not work.
So I think the problem come from plesk 12
This is how I process to configure my website on plesk 12 :
1. This is a 1&1 domain and an OVH dedicated server.
So I configure DNS like that :
1rst name server : nsXXXXXX.eu
2nd name server : sdns2.ovh.net
2. On plesk, i click on "Add New Domain"
Capture : [URL] ...
3. I wait for DNS propagation but it doesn't work...
Capture of DNS checker [URL] ....
Just upgraded from Plesk 11.5 to 12. (CentOS 6.4)
Everything is working but when I reboot the server using the Plesk CP it never comes back up. No CP, no domains, no SSH.
If I reboot it using the 1&1 CP it re-boots fine.
SETUP:
CentOS 6.3, 64 bit.
Plesk 11.09, Update #10.
I enabled Watchdog in Plesk.
It works fine.
However, it doesn't start up by itself after a server reboot.
I can start it manually with the following command:
/usr/local/psa/admin/bin/modules/watchdog/wd --start (which I have done by adding it to /etc/rc.local)
Shouldn't Plesk do this automatically?
Two of my domains experience random DNS problems; I've had frequent complaints from eastern countries (and sometimes experience the problem myself) that at seemingly random moments the domain will not resolve. For the eastern countries, this may go on for days at a time, while for myself (in the US) it's no more than an hour or two. While it may work for some, it randomly goes down for others.
