Server Slow down

Hello all,

I have 2 CentOS 4 virtual servers running on a box [ physical machine ] that is hosting 3 other Linux VMs. Intermittently, only the 2 CentOS VMs will be slow down so much that they become inaccessible. 2 or 3 minutes later, they are fine as if nothing has happened. I am not very experienced in Linux so my questions are :

1. What could be causing the slow down of those machines given that this started about a month ago without any changes, hardware or software, to them.

2. I tried inspecting the system log file but for the life of me I couldn't find it. Where is the system log file located in CentOS install. I don't have X server running so I am using the command line.

Thx for all the help in advance

On a standard [i]CentOS[/i] system, the log files can be found in the [b]/var/log/[/b] directory.

Alan,

Thanks for the response. I couldn't find anything in log that points to the reason behind the slow down.
Any idea why the server would slow down intermittently ?

Thanks

Sorry, but from the information available, I have absolutely no idea.

Perhaps precise details of the hardware, some information about the other VMs running on that hardware and the virtualisation software you are using [i]may[/i] enable others to make some suggestions . . .
