I have a few Ubuntu Server virtual machines with 256 MB of ram allocated, which use Postgres 8.3 and Catalyst (under apache w/mod_perl), and they run fine for single-user usage of the application. (They're for testing.. I also have some catalyst+postgres apps running on live sites, but I've never tried those on so little ram!)

I'm surprised the entire machine locks up -- have you tried diagnosing what is going on when that happens?
(eg. checking log files)
Is it defnitely an OOM problem, or something else manifesting?
