hi,
i've not reconfigured linuxthreads.
/proc/sys/kernel/threads-max has 57344. At the time
when the machine hits 100% CPU, apache processes are
taking most of the CPU time, and i have around 250
processes on the entire system, with around 10-15
running processes. mysqladmin status shows me around
15 mysql threads running. Agreed that something like
this should not happen, the CPU touching 100% is not
an acceptable situation, but what i'm worried abt is
mysql crashing. If the OS goes for a toss, i know
that it is a problem with the load, but mysql is
getting something like a 100-150 queries at that time.
Tx.
