Unfortuntatly I can't remove all 3rd party products - if I do, I don't have much of a testcase, because then I don't have an app to test against. Like I remove DCO2 I only get errors, because lots of data is used in presenting layouts, pages etc. If I remove formulator, I get errors, because the pages that I would need to test, give errors. I can remove TransparentFolders and possibly strippogram, but we have previously done tests to see if TP slowed things down, but got no colcusive results (and no decrease in core dumps either). I can also remove Strippogram, but it is a late addition. We have had core dumps since the days of borked Python 2.1 and Zope 2.4.3/2.4.2 - culprits have been, in the past, old versions of DCO2, previous versions of Python and old versions of exuserfolder (which we don't use anymore). The only thing I have to go on is that as son as there are lots of PythonScripts involved thins star to deteriorate. I might also add that changing zope to use only one thread, as has been mentioned as a possible workaround with pesky DA's, is not a realistic option - on the contrary I need to bump up the thread count to around 10, to be able to use more than 4 concurrent SQL queries. I am at loss here - I don't even know where to begin looking for errors. Maybe it's our app that is faulty (I know for a fact that around 40% of it could be done in a cleaner way). Oh, and the icing on the cake is that allmost all of my PythonScripts need to be recompiled, all of a sudden. All I did was to pack the ZODB, and copy it to production environment. The app is only about 6 megs in zie all in all, so I wouldn't expect any serious ZODB corruption (as the bulk of the data.fs is moslty app-logic, I would expect corruption to show itself real fast, if it existed). So, apart from killing myself, is there a way out of this? Or at least a general direction in which to start looking for possible solutions? I have to deploy this app 2 days ago, so I 'll try to setup as many safegueards as I can. After that, in a sanndbox, I'll set my app up with as few 3rd party extensions as possible, and see if it helps. Any insight is greatly appreciated. I have saved coredumps if anyone would care to dig thru 20-40 megs of data :-).
