[PLUG] Re: Why am I running out of memory?

The 2.4 kernels have a 2G memory limitation per pid.  I ran into this same
problem performance tuning a mysql database.  Our solution was to break the
process into multiple processes.  Parent/Child isn't good enough either, as
the parent pid will reach the 2G limit and then hang.
