Now the core files for example (core.18920) files are filling the server, here is a shot
-rw------- 1 someuser somegroup 3.9M Mar 17 16:15 core.18920
all server account have that files, all users how running php files in there websites have the core.**** files and all websites quote are going to be excceded
I guess the problem from apache, i do rebuilf using whm, but the same problem
Files such as core.12762 keep appearing in the root web directory. Amount of core files appearing seems to be proportional to traffic. On average one core file per few million php requests.
Will appreciate advice on how to troubleshoot this issue, or how to disable the core dumping. As it is one error per few million requests it does not seem significant enough to spend several hours troubleshooting.
I`ve found some core.xxxxx files in some directories under some of our accounts.
I think those should be a trojan, Is it right?
* Many of those files are 0bytes, But some others are about 2-3M.
And how to remove those? What should to do to have those removed successfully.
This is a part from one of those files:

They also filled up a huge space, what are these files for?
Just noticed quite a few large Core. files within one of our websites (within a sub folder of public_html). Anyone knwo what these are and how they got there?

After being screwed by Dawson and fumiNET, my server was reinstated by BurstNET (thanks BurstNET). However, the few interactions I had with them gave me the impression that I would be better off with a slightly higher level of support, so I decided to go with PC-Core.net. Cody is a decent sort of chap, and was very patient and helpful during the pre-sales period. I wanted to just transfer my BurstNET (nee' fumiNET) box to PC-Core, but that couldn't be done - so, a new box was deployed and everything was transferred from the old box to the new box.
However, things just never seemed to click right. I cancelled my server with PC-Core due to the following reasons:
initial configuration was incorrect (misspelling of domain/host name, mistakes, incorrect settings)
box was assigned banned (dirty) IPstech support informed me that I would have to report these myself to the banning agencies
support tickets regarding this issue were closed before being resolved
after Cody's intervention, new IPs were finally assigned, butthe IPs were assigned on the day that I requested that it not be done
configuration of box with new IPs was incorrect (misspelling of domain/host name, only one of 5 IPs was configured, incorrect settings)
box was down for nearly a week (which must certainly have exceeded the stated limit in the SLA)no compensation for downtime was offered
my request (twice) for compensation was ignored
To be fair, during this whole process, Cody was always available and intervened to get things on track. However, Cody's intervention should not have been necessary, and worse, my requests for SLA compensation (sent directly to Cody) were ignored. This is unfortunate since the box (just before cancelling) finally seemed to be OK. I just got to the point that I had had enough - and I certainly felt that I was entitled to compensation for the headache and downtime.
I nearly decided to shut down my operation due to frustration, but I decided to give it one more shot and decided to try a fully managed VPS at WiredTree. I will post my impressions in the VPS forum regarding WiredTree - but in short, WT is ** AWESOME **.
Yes - capitalized, italicized, bolded, underlined, and flanked with stars.
I must also mention Josh from VolumeDrive. During my despair, and the search for another host (before just packing it in), Josh provided valuable advice and insight. Months earlier I went through a pre-sales process with him before eventually deciding on fumiNET, and in spite of this, Josh just picked up from where we left off - even though it was fairly evident that I wouldn't be going with him. I'm hoping that my sites become successful, just so that I can justify getting a server with VolumeDrive. THANKS JOSH
About to pickup a server strictly for use with MySQL databases.
Right now there's zero price difference between the Intel 5110 dual core and the 5310 quad cores. Looking around a bit online, it seems like the quad core is of no benefit (or lesser performance) than the dualie. That sql cannot take advantage of it yet.
Is this accurate? If so, where do quad core CPU's shine at this point in time?

are there any providers out there that will offer a core to you server, i.e. dual qauad core machine would be runing no more than 8 with each account have a single core each?
View 7 Replies View RelatedI've not posted feedback for past providers that haven't been so good, but due to bad service and a lack of refund after nearly 2 weeks, I really need to post my situation.
The site is pc-core.net, and they have had some fairly decent offers going on WHT.
After 5 days of good service from the dedicated provider PC Core, I ran into possibly the worst 10 days of running a website I’ve ever encountered and a further 12 days without a refund.
Here’s my story.
I signed up for a dedicated host in September, and my machine was made active on 25/09.
The server went down 5 days later on 30/09, and it took more than 24 hours to get it back up. So now we’re running on late 01 Oct 2008, but slow and sometimes unresponsive. The site then goes down completely on 05 Oct 2008. A response on 06 Oct 2008 saying they’re looking into the situation. Had to then wait 2 days, and post 3 replies to get a response on 08 Oct 2008.
One last response on 09 Oct from support, then I had to update the ticket 10 times to get another reply on 14 Oct 2008.
The server was down for 9 days with little to no response from the tech support, despite me continually trying to contact them.
Server back online briefly, then down again on 15 Oct 2008.
On 16 Oct 2008 I placed a ticket applying for a refund, which should be instant and my account cancelled instantly. Refund request finally got through on the 18th, server down but my account on their site is still live (so I’m still being invoiced via PayPal).
Their refund policy:
If for any reason you are unhappy with our service, and wish to leave during the first 30-days, PC Core will refund your purchase price less applicable fees in full.
It’s now 30 Oct and as I write this I’m still waiting for a refund (12 days waiting for a refund, still no response), still waiting for my account to be cancelled and I’ve posted numerous tickets asking for an update during the last 12 days.
I was told that they may pay me for the remaining days I had left after cancelling.
Surely a full refund is in order? Or at least the downtime and remaining time for the month.
I’ve been with 4,5 dedicated providers in the last two, three years but I have never seen any take more than 5 days to respond to server downtime, it’s appauling. The only thing going for the provider during my month with PC Core was that the staff were kind and helpful when they were around to give it.
I have a server running Fedora 4 and WHM/cPanel. I would like to upgrade the linux kernel to the latest version, so mosey in via SSH and type "yum -y upgrade". It downloads a few things and tells me everything is hunky dory.
Now, the version it says it is currently running is: 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006
Is that the really the newest version available? Maybe I'm confused as to how this works, but if I go to kernel.org it tells me the most recent stable version of the kernel is 2.6.24.3. Is this because I am running FC4?
I have a big problem with this company. check this ticket:

Hi Marco,
I am sorry to inform you, but the data center screwed up and reformatted your server and reinstalled Windows. They misunderstood what we were telling them. We were talking about another server. I apologise and am seeing what I can do.

We are hosting our software system which do calculation and file manipulation.
Now we have Intel Core 2 Duo E6750 and would like to get Intel Core 2 Quad Q6600 to increase our system performance.
Also we have other choice, get Intel Xeon E5405 Harpertown 2.0GHz
to replace two above.
I think it is better to have one server box because one box easy to manage than two. Also Harpertown is much faster than these two together.
What is your opinion?

I'm running a message board and it looks like I've outgrown the low end xeon 3040 1.86GHz dual core server, and the bulk of the CPU load is going to mysqld. I'm debating between offloading the DB to a dedicated server vs upgrading the existing server and hosting the web server and db on the same machine.
Any thoughts on the better approach? fwiw, the load from apache seems next to nothing right now, but I am also planning on adding an SMTP server for user registrations and general support email.
I'm also not super familiar with dual-core and dual processor machines. Does shifting mysql to a dual core or dual proc machine help (vs a single core/single proc machine)? since there is just one mysql daemon, does having a second core or proc. buy me anything?

Core 2 Quad 6700 [ OR ] Core 2 Quad Q9450 | Which is better
I cant decide between
Dual Processor Single Core
Dual Processor Single Core Xeon - 3.00GHz (Irwindale)
Or
Single Processor - Quad Core?
Single Processor Quad Core Xeon 3220 - 2.40GHz (Kentsfield)
My site needs "raw" processing power due to the applications it runs. ram (over 2 gb) and hdd are not that important to me.
could someone point me in the right direction.
Which is a better option? Both priced same, I know with the Xeon 5310 the possibility of upgrading to dual cpu's.
Quote:
Single Processor Quad Core Xeon 3220 - 2.40GHz (Kentsfield) - 2 x 4MB cache
Single Processor Quad Core Xeon 5310 - 1.60GHz (Clovertown) - 1 x 8MB cache
Which would give higher performance in a shared web hosting environment?
I am going to buy a new server and I am unsure of which route to take.
Basically the cost is identical for a Dell server with:
1 AMD Operton Dual Core 2.4Ghz
OR
2 AMD Operton Dual Core 2.0Ghz
What is the felling? Does the 4 cores out weight the extra 400 mhz per processor, but only having 2 cores?
The server will be running:
Windows 2003 Standard x32
Plesk 8.2
IIS 6.0 [ Application Pools Setup ]
MySQL
Microsft SQL Express 2005 [ONLY CAN USE 1 CPU/CORE]
MailEnable
Can my applications even handle/utilize four cores?
what is the fast and best way?
