What happened here is a fatal signal (usually SIGSEGV) that
hit one of you Zope threads.
A Python bug is responsible that Zope enters this broken state.

The bug will be fixed in Python 2.4.
A patch is available for Python 2.3 (but you must apply it yourself
and then regenerate Python).


The primary problem however it the fatal signal.
Attach your running Zope with "GDB" (read about its "attach" command).
Let Zope continue. When the fatal signal hits Zope, "GDB" will
get control and you can analyse the program state.
