Exact same config on other webservers wtih really low cpu.
Memory checks out fine. Mysql connection to db checks out fine.
IO is fine.......running out of ideas.

I even recompiled his kernel optimized with 256 maxusers.
That did not help either.
looking at apache error log i see alot of
[Mon Feb 26 15:12:50 2001] [error] (54)Connection reset by
peer: getsockname
so i guess i will ask about getsockname......i have experience this before
when maxclients was set to low. That is not the case here....running out
of ideas.
