I'm having the same problem as everyone here. My server has been up and down many time for almost two weeks now. I've tried the ulimit that was suggested in this thread, its been 3 hours now, didnt get locked up. We're using proftpd but still crash.
My OS is centos4.4 and I've tried changing the kernel and below is the list of kernel i've tried
CPU : Dual Opteron 248
RAM : 4GB
the datacenter gave me a kvm to use for a shortwhile and here's what I get before it locks up.
From the looks of it, im having problem with quota or is it I/O access?
If its I/O access, i've search in google and there are ppl claims that after they upgraded the kernel (not rpm) their server went well. I'm gonna try this option next.
would appreciate any suggestion. TIA
