Stephen,Thanks for the interesting tips, I did not know that. I'm copying the user-lists because these may be of general interest to the community.

The default number of simultaneous ipcs queues allowed for any user is set
to only 8 in RedHat.
You may want to increase the value to 32.
Check this by running sysctl as root:
sysctl kernel.msgmni
You can set this value in the /etc/sysctl.conf file, so that it is the
system default after a reboot.
He are some details from my development machine:
[root@gempak3 root]# cat /etc/sysctl.conf
# Disables packet forwarding
net.ipv4.ip_forward = 0
# Enables source route verification
net.ipv4.conf.default.rp_filter = 1
# Disables the magic-sysrq key
kernel.sysrq = 0
kernel.shmall =4294967295
kernel.shmmax =4294967295
kernel.msgmni = 64
[root@gempak3 root]# sysctl -h
usage: sysctl [-n] [-e] variable ...
sysctl [-n] [-e] -w variable=value ...
sysctl [-n] [-e] -a
sysctl [-n] [-e] -p <file> (default /etc/sysctl.conf)
sysctl [-n] [-e] -A
[root@gempak3 root]# sysctl kernel.msgmni
kernel.msgmni = 64
