The problem below is zope not responding to requests but still beeing running. I made a funny experience recently:
One of our low load Zope installations went into this hanging state regularly. I had the impression, it happened every day. Then I activated a checker, that checks availability every 5 minutes. The problem went away. Since then, Zope never hung again. Maybe, Zope does not like to be lazy? Dieter

We run our Zope installations under monitoring by NetSaint. My GSM phone rings when Zope hangs, quite irritating. Anyway, NetSaint checks a couple of times per minute, and we nevertheless had Zope hangs. Yesterday there was an explicable one: we do whois lookups, and the Belgian registration authority somehow dropped our SYNC packets from the whois connection attempts. By the time <number of threads> people tried to do a whois, Zope became of course unresponsive (and my phone rang). Just adding useless datapoints.... ;-)

Joking aside, I'm almost inclined to agree with this. Our server that has a habit of dying can lie dormant for a few hours and that's when it seems likely to die most. Am I mad or is this worth looking into? cheers, Chris

Out of curiosity, what are you using for your checker? ./jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
Hi all, I have the same problem. My Zope hangs one or two times a week. I also was thinking to write a program to check if zope is up, but I don't believe this is a professional way to solve this problem. Maybe using Zope with apache? Someone have tried it? Jose Jason Cunliffe wrote:
