Hi.
The default values for kernel.shmmax, kernel.shmall, kernel.shmmni and
kernel.sem doesn't seem enough for apache2 (and for php "make test" for that
matter) and friends. Could we please set some decent values in the
/etc/sysctl.conf file to solve future issues, hopefully also for 9.2 if it's
not too late?
I know very little about hardcore kernel tweaking, but found some info on the
net:
http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/admin_user/kernel-resources.html
http://technet.oracle.com/sample_code/tutorials/idclinux/OracleonRedHat8.html
For my tests I had to raise the values for kernel.sem in order to get apache2
to start with the new apache2-mod_python installed. Here's my current
settings:
Use half of RAM:
# expr `cat /proc/meminfo | grep "Mem:" | awk '{print $2}'` / 2
# sysctl -w kernel.shmall="130973696"
# sysctl -w kernel.shmmax="130973696"
# sysctl -w kernel.shmmni="4096"
# sysctl -w kernel.sem="512 32000 32 512"
# rpm -qa|grep apache2

There is a thread about this (kernel.sem) on the mod_python mailinglist here:
