<narrator voice="kosh">And so it continues...</narrator> I've finally recompiled all pythonScripts (all scripts and ZCatalog tricks I tried before didn't know how to get the PythonScripts inside the ZClasses. BTW, if anyone is interested, I can send you the scripts I used to recompile all pythonScripts inside ZClasses). But it still segfaults (and it doesn't seem to be any more stable, so there Anthony :-). At least I got a cleaner stupid_log_file, no more "needs recompilation" messages :-) Matthew, thanks for taking the time to gdb the beast with me. Did you come up with any instrumentation I should add to Python or Zope to get what it is that Python is trying to resease twice? If you want, I can arrange a MySQL-less period during production so that we can capture the crash in a cleaner environment. Speaking of instrumentation, since the gremlin seems to be threading related (it stops with '-t 1'), it might be useful to serialize certain parts of the execution path with semaphors, like the path to the restoration or the execution of PythonScripts, the path to the execution of SQL queries, etc. this means running with small locks in certain sections instead of the big '-t 1' lock (which is not really a lock, but you get the picture :-).
