Do you think a too low limit on user processes could be causing the problem?

We have had similar crashes (server process terminated with Bus
Error). This is running 8.2.5 on OS X (Tiger, intel), with about
130-140 connections, but the process count limit is 1000. Any reason
why the process limit should be vastly higher than the number of
connections?
