Thank you Gerald and Perrin -

I think my core dumps are being written to /dev/null ;)
Everthihg I tried to produce them failed (ulimit, permissions,
etc.).

But I did get a backtrace via Gerald's instructions. Before
dumping it on you am trying to get back to a stable system.

I have already:

  rebuilt _everthing_

  moved my test server
to the _same_ machine as production (that means that all
non-specific libraries used by production and test will be
for sure the same, right?)

  dropped back to Apache 2.0 cvs (from 2.1)

  dropped back from Embperl cvs to latest beta

Results are the same: test soild, production segfaults.

I'll drop back to perl 5.8.3 and rebuild everthing (again)
tonight. If that doesn't work, I'll go to the BT.

Don't you hate it when a bug or misconfiguration isn't
consistent!!!

Aloha => Beau;
