I forgot to mention... our neither our z2.log or stupid_log show anything upon freezing. afterwards the stupid_log shows the failed transaction cleanup, but that's it.

And interestingly enough, they don't seem to show up on any of our servers except the 2.3.0 upgraded to 2.3.1. 1. Hangs on anything from Pythonscript or dtml 2. top shows no significant mem or cpu usage 3. threads are all unresponsive 4. restart usually yields a .trX file (an aborted transaction I suppose) Any ideas? Maybe it was something "fixed" in 2.3.1? The causes seem to be somewhat different except that they all modify the ZODB.... Tim
