RE: Crash

["Tony Johnson" <gjohnson showmaster com>]

I interpret the crash like this...

1. Someone went to check their mail
2. The pop server had to spawn a process (authentication/delivery/or
whatever)
3. It called mmap to allocate memory for the spawned process
4. Crash!

Could be bad code in pop server.  Could be bad memory.  I would recompile
kernel and pop server just to make sure that it doesn't happen again.  Also
if you are changing $CC / $CFLAGS options, use the defaults.
