[Zope] Zope hiccuping

Wed, 7 Nov 2001 15:46:44 -0500

OK, did a ./configure --without-py_malloc with python 2.1.1 and it didn't
take care of the problem.  Still getting:

2001-11-07T20:30:11 ERROR(200) zdaemon zdaemon: Wed Nov  7 15:30:11 2001:
Aiieee! 9400 exited with error code: 11

Yes, it did compile (make clean, configure, make) and the Makefile has the
argument --without-py_malloc
The start script is pointed to the newly compiled python and I'm still
getting the same error.

Aack!
