Description MF Lee 2004-09-27 08:40:08 UTC

Description of problem:
The server running service of http/ftp in two week ago. After system 
hang, the log files shows kernel out of memory. Is it kernel problem? 
Can I upgrade latest kernel or other for fix memroy issue?

Comment 1 Larry Woodman 2004-09-27 14:38:25 UTC

MF Lee, the problem here is that you have exhausted all of the swap
space and over-committed physical memory.  At this point the kernel is
backed into a corner and has no choice but to kill processes in an
attempt to recover physical memory and swap space.

Please add more swap space to your system and the problem will go away.

Thanks, Larry Woodman
