Hi,

Thanks for the tip, it lead me down a path of investigation that lead to teh
ThreadStackSize directive for mpm_worker. It looks like ThreadStackSize
would allow me to adjust the stack size for Apache only (my ideal
situation), however this directive doesn't seem to affect the actual memory
utilization of Apache -- for my tests I've tried using several different
sizes of ThreadStackSize, from 1024 to 8196.
Is there a certain magic for using ThreadStackSize? The mpm_worker doc for
that directive is rather unclear.
The same happened to me. Apache ignored the value given in
"ThreadStackSize". Then I realized that the unit of the value specified
for "ThreadStackSize" seems to be "bytes" not "kilobytes".

works for me.
.max
Thanks,

Hello all,
On the SLES 9 and Red Hat systems (glibc 2.3), 'ps -ea -o
"pcpu,vsz,args,pagein" | grep -i httpd | grep -v grep' reveals that
apache is using apx 313MB of ram. No problem here, about 2.5MB per thread.
On the SLES 10 system (glibc 2.4), same Apache build and settings, I
find that Apache is using apx 1179MB of ram, or about 9.25MB per
thread. A 370% increase in memory utilization. This memory
utilization can also be confirmed via top, free, or whatever other
flavor of utility you would like to use.
Linux default stack size is something very large when ulimit -s is set to
unlimited. Try ThreadStackSize or ulimit -s <something other then 8M>
