I have in my possession a new server which is running cPanel. For some unknown reason it keeps crashing about every 4-6 hours where I must get a remote reboot done.
Its starting to annoy me that I'm unable connect to anything. What I suspect is high disk red/write. As what I'm finding is over 10k blocks being written per second with only 300 being read per second. I also am not seeing any bandwidth out/in usage being high.
I have a dedicated server with NyNOC and earlier on today the server dissapeared off the net, wouldn't respond to ssh, http etc, nor pings
I submitted a ticket and the server got rebooted, went through the FSCK check and came back up ok, but now I'm concerned as to what caused it Andy the technician said he couldn't find out the reason why and neither can I I can only put it down to PERHAPS faulty hardware somewhere?
The /var/log/messages file doesn't say anything useful, the last entries show..

You can see it was down for some 6 hours, but I can't find a reason why Diskspace is ample, there's no odd programs/scripts installed (it's a Centos server running whm with CSF firewall)
I reboot my cpanel server twice last night and it had crash
I am now running e2fsck and it's trying to fix the inode thing.. i've been pressing <y> 10000 times! Poor thing my fingers cramp
I've been thinking to mount my primary drive into another cpanel server (not a fresh server) as secondary drive and restore from there. The question is how? I need detailed steps by steps as it's urgent for me..
I just got a new server the other day, installed cpanel and all my usual stuff in it.
Then I started transferring some accounts off my other server on the same network. It would transfer small accounts ok but I have this one big account,. the sql is like 300 mb. It would get to the restore on it then the server would crash and be totally unresponsive.
It has to be manually rebooted at the datacenter. There is nothing in any logs. At first I thought it was the load getting hi and doing it but I ran the unix bench and got the load to 14 and it didnt hurt it.
It only does this on restoring big sql db. At the dc they say the screen on the console goes blank.
Ive done looked and cant find anything in the box. Its actually the same exact setup I use for my other servers.
So the dc is looking at it today. Has anyone ever ran into a problem like this and if so what was the cause?
The Apache server on one of my box crashed last night and the log file simply states: [Fri Mar 09 23:51:49 2007] [notice] caught SIGTERM, shutting down
One thing puzzled me is that there are a couple of symbolic links created in Apache home directory:
My server is constantly crashing (halting to dead) and needing reboot literally every few hours. I cannot trace the cause of this whatsoever. Please help out.
CPU/Memory/MySQL Usage shows no accounts in red or yellow zone ....
I have a lynix root server with 1and1.com and recently the server has been going down I have no access to FTP/the sites or root. Their support tells me to look in var/log but im not sure what file to look in or what im looking for as far as to why the server would crash.
So far my solution has been to re boot the server and it has been working but i need to find the cause of this...any suggestions on where to look or what to look for?
I have a Linux server running some reasonable setups:
Opteron 180, 4 GB RAM, running 8x 36gb 15k scsi with hardware raid 10 -- this is one of the servers from WebNX advertised here not long ago
Running CentOS 4(?), Apache2/MySql 4/PHP5.2, the normal stuff.
I have only one main site on the server, which runs a pretty old PostNuke CMS in Chinese (0.7.2.3 Phoenix) + PNphpBB2 + Gallery 1.5.7 (all integrated into PostNuke). This site is pretty light in "human" traffic, getting about 20K hits per day.
Now, the problem I have noticed with this site, is related to the many MP3 files stored in the Gallery albums. There are lots of HTTP requests to these files, most maybe from Chinese search engine bots (judging from IP), that slows the server to a crawl and even crashes Apache. This happens in the late hours here when it's day time in China. As a matter of fact I just did a reboot, and in 5 minutes there are more than 1000 HTTP requests to MP3 files resulting in a traffic of 2.1+ Gb. So within minutes, the server is brought to its knees again and I can't even get the "apache status" from CPanel now: "Unable to retrieve apache status".
The company that manages the server for me said there's no security problem here. We have installed an Apache extension to limit the number of simultaneous requests to media files to 1. However that doesn't seem to help.
I have a problem. to buy dedicated server but I don't really know what to buy. I need some kind of stress test for server so that I can be assured that my website won't crash when it will be on front page of digg. Does something like that even exists?
The company I work for unfortunately runs their site on a IIS server. I want to install some forum software, vBulletin or phpBB onto the server and run it on the same site. PHP of course needs to be installed to do this.
Boss is worried that putting PHP on same server as ASP might take down the site if something goes wrong. What are the odds of this happening if I follow directions and what steps should I take to install?
My server stopped responding to everything from http to ping and I had to do a hard reboot on it.
Now, I'd like to figure out what happened but am not sure where to start. I've been sifting through /var/log/messages but can't pin point what I'm looking for.
We had some issues with old server hence we migrated some websites to another new server from our old server.
We did a backup of all existing webfiles and database from old server and transferred the same to new server, a manual transfer few weeks ago.
However, we were not able to backup our awstats logs for this domains, can someone guide how to transfer awstats from old server to new server?
We cannot perform an automated transfer from old server to new server now, is there some way we can migrate our awstats from old server to new server for this domains?
After a full year of operation, I think I need to delete some log files. What types of files can I safely delete (and is deletion the best option, i.e. will the files be regenerated from zero length?)
For example, my server's error_log file is 193 Mb and my access_log file is 14 Mb. Can I "rm" them both?
Are there any other such files I can safely delete that occupy space on the server?
One of my servers stop generating server logs, ftp logs etc all of a sudden since yesterday. It is a windows IIS 6 server, anyone have any idea on how to repair?
=We are trying to integrate eBay.com feeds into our site and for some reason we are not able to get expected results on current shared hosting server. We tested the same on another server and we are able to get the right results. And the current host doesn't allow us to access the server logs unless we upgrade the account to VPS and Dedicated server. But we are pretty new to launch the site, hence we don't want to buy any VPS or Dedicated server for now. Now we are looking for another shared hosting who can offer to access server logs.
Hi, today i was banned from hotmail aparently someone enter our server to one account of one client and sent spam all over the net...
platinumservermanagement already told us the name of the account used and we change the password,
can you please tell me where can i check the out mail logs (am using centos & exim) to see if anyone else is sending out spam? or the number of emails sent?
Is there any way to disallow connections to SEND mail FROM my server to specific IPs? (Similarly to how you can limit connections to sshd from certain IPs)
I realize I cannot disable everything completely, as yahoo and the likes will have to connect to deliver mail. But no one of any use is going to try and connect to send mail, but a spammer.
No one has gotten in and abused it as of yet (knock on wood), but SMTP is being restarted at random and I can only imagine that this is being caused by one of these scumbags probably ddos'ing me. It takes eons to browse these logs, even if they restart via logrotate periodically!
