Hi Daniel,After performance tuning of apache, the mem usage is now more managable. However, the apache still experience intermittent crash which we suspect is due to certain PHP module running in our joomla website.
If it really is the PHP module that is crashing it, there's really no other way to test that theory unless you disable it and see if the crashes persist.

Not sure if you noticed or not, but all of your memory is not actually showing up as available to the kernel. Are you running a kernel with "bigmem"-style support? If not, you're missing out on half of your RAM.

There is always the 2.2 branch, which I'd recommend trying out if possible. Perhaps this is a locked down distro release with only the older version available (RHEL/CentOS?).
