> Chris, do you have a recent version of ZODB? It's all pretty bog standard. Zope 2.3.1b1 which was running fine with ZEO 0.4 (well except for the ZSS Weirdness I posted about a while back on this list) I upgraded Zope to 2.3.1 final and have been running on that for a few days. Today I installed ZEO 0.5 to give it another go and got this. HTH, Chris (out of his depth ;-)
