You COULD have a flaky Power Supply such that high rail load is bringing it out of spec.   Be careful swapping one tho.   Some of the older Dells use a proprietary pin-out on the PS connector.  It's the SAME connectors, but wired differently.  LOOK at the colors going to what pins if you choose to test this theory.  If it this type, you'll smoke a PS tester if you plug it into it.  Bulging Caps ( a well know issue with Old Dells) on the MB could be a sign of unclean power too.

My 2 cents

:-)

Is it a VPS or on bare metal? I've experienced similar behavior on VPSs, still not sure why,

Nope - everything just stops - ping waits for a response, web services just wait for the server, file transfers stop and wait.......as if time just stopped for the server, then starts again without any errors being evident.

Can you do access any other services hosted by the server during this time? Or even an extended ping?

I have a headless server running Linux version 2.6.32-5-686 (Debian 2.6.32-45) (dannf@debian.org) (gcc version 4.3.5 (Debian 4.3.5-4) and no X or window manager, and I have noticed in the past couple of days that when I ssh in the server it occasionally stops responding for a minute or two, then comes back as if nothing had happened. It is a random event - maybe once an hour. I cannot find anything in the logs - no error messages. There is nothing wrong with the machine where I initiated the ssh session, and it is not connected to ssh. The server completely stops responding, then comes back as if nothing had happened.

How would I go about diagnosing this problem?

Thanks,

Mark
