This thread's not over 'til the fat lady sings. OK, so apologies first: Paul Winkler's comment in this thread was nearer the mark than Tres Seavers. clienthome is not relevant to where caches are created, and of course I need zeo-client-home. Problem is now that zeo-client-home seems not to

Thanks Chris, looks like I may have been bouncing messages. I did not see your earlier reply. Your comments regarding file locations seem dead on. Sorry for the noise on that topic. I'll try the naming change. I've had to go back to 2.7.1 due an another error, below. (Yes, I did rmpyc on all

Thanks Tim and Chris! - You were both dead on in so many respects. Chris, There was a correlation with flip in the logs Tim: looks like once a None occurs it sticks. Source of the problem was an old cache file (1-None-1) that could not be overwritten by the current uid running Zope. (That's the

Thanks a lot for the confirmation! I haven't seen this problem crop up in several days myself, but that may just be due to the fact that the ZEO cache hasn't flipped. (Tim, yes, when it does happen, it only happens once; then the server is restarted by my customer to get the site going again, so

Thanks, Chris. We're fronting two Zopes with Pound for load balancing. I can't see there would be any connection with this error. But I mention it in case there's a pattern. Also, the database came from 2.7.0 and an earlier python. This looks like resource starvation to me. The servers run for an

[Chris McDonough] ... I think the problem is related to ZEO client storage cache flips. Me too. The 3.2 ZEO cache alternates between two cache files, in the two-element list self._f. Both elements are initialized to None, and the index of the current file in use (0 or 1) is in self._current.
