Right. Though you can also just increase the xcache.size and the xcache.var.size to fix the problem if you haven't maxed it out.

The default is set to xcache.size=32M and xcach.var.size=0M.

My board requires that my xcache.size=140M and my xcache.var.size=2M. I also have my count set to 2 for the number of processors.

As you can see, even though my xcache.size is 140MB and the xcache.var.size is 2MB (even though the variables get most of the hits), this is still way less than the 4GB of system RAM on my server. You do not necessarily need to upgrade your server to fix your OOM problem but simply change a couple of variables in your php.ini.
