Alright Zopers, I'm looking for a hint, a suggestion, just about anything would help since I can't, for the life of me, figure out what's wrong. Here's the run-down. We are running Zope 2.2.0 on Solaris, and we're running it through Apache + SSL. We're using a PostgreSQL DB with the ZPoPyDA. We are also using FSSession 0.4.0 for session management. Previously, we were using Zope 2.1.6, accessing ZServer directly, and using FSSession 0.3.1. Here's the problem. Previously, when we were accessing ZServer directly, Zope would spontaneously quit. No reason, it would just die. Restarting it would bring it back up, but minutes, sometimes hours, sometimes days later, it would spontaneously die again. I asked the list, but no one had had such problems (except Dieter, but that was an Oracle problem). So now that we're running it through Apache, we're still, apparently, having the same problem. What will happen is that every once in a while (more frequently with more traffic), Zope will hang indefinitely. The only way to get over it is to restart Zope. So apparently, the ZServer (which I guess takes requests from the pcgi process), is still going down as before. The question is, why is this happeneing? Or, more to the point, how can I figure out why it is happeneing? I looked through the Zope logs and the Apache logs and found nothing useful. I've been thinking that it might correspond to a heavy database access. Perhaps there's a problem with the ZPoPyDA. Or maybe it's FSSession (which, incidently, doesn't seem to be expiring cookies correctly). Or maybe it's a compatability issue with Solaris. I really don't kow, and I don't know how to go about finding out. So any help anybody can give me would be fantastic. If anybody's had any kind of similar problems, or if anybody has any suggestions, it would be much appreciated. I've racked my brains trying to figure it out, and I just can't. Thanks.
