[Zope] Re: Zope crash - Informations

[Chris McDonough]

Jean Pierre,

If you don't see crashes in line 74 of select_trigger.py, this is likely 
a different problem.  In which case I suggest trying to narrow the 
problem down further by turning on "big M" debug logging and using the 
requestprofiler.py script in the utilities directory to analyze the 
logfile during a series of crashes to see if you can determine a pattern 
to them.
