this is a 4GB memory machine
shmmax=33554432
shmall=2097152

I'll discuss these with my sysadmin.
thanks again....mac

Hi Mac:

   What does  "cat /proc/sys/fs/file-nr"  report before and after you 
run  qmaster?

   Also, if "cat /proc/sys/fs/file-max" is under 100,000, you might want

to boost it up a bit.

   Also look at "cat /proc/sys/kernel/shmmax", and "cat 
/proc/sys/kernel/shmall" .  You want shmmax about the same size as your 
system memory, and shmall should be similarly sized.

Joe
