Hello Everyone, We are using Zope for one of our sites but Zope died as of yesterday. (refer to Chas' posts) This was totally out of the blue and is quite shocking. (Zope is still down after 24 hours) The question I'd like to raise to the entire list regards Zope's stability. We are running Zope integrated with Apache off FreeBSD3.2 . As far as I know, this is not such an exotic setup (probably rather common?). As Chas explained previously, Zope just suddenly died. Teodore also had the same error occur and solved it by rebooting his server. How often has this occured with other people? Are there any good solutions regarding providing a backup in case Zope does die? (and keep the site running) Are there any serious Zope instability issues which need to be discussed and alerted? TIA, Thomas

I've experienced some Zope 'hangs' on my Red Hat 6.0 Linux box. The Zope process would still be running but it'd not be responding to anything. Oddly enough this only seems to occur to my non-debug mode Zope's. The Zope I've been running under 'nohup' in debug mode hasn't given me such problems, though I've been using that for developing products so it's been restarted pretty often.
Are there any serious Zope instability issues which need to be discussed and alerted?
As a production Zope site will soon open here (finally) I'd like to hear more about this too. Regards, Martijn

That's really bad news. If this persists with Zope 2.1, then please bug us at support@digicool.com. Jim -- Jim Fulton mailto:jim@digicool.com Technical Director (888) 344-4332 Python Powered!

yeah, but for my luck it wasn't a production server but just a home computer

Good point. Anyways, what I am frustrated of is a good debugger for Zope. I've just downloaded DDD & pydb to give them a try but I am interested in using ZMonitor (not much docs about it or did I miss something?) btw, How exactly is MrCreosete (spl?) working and how can it be used? Second, ppl must undestand that they are using a *free* product. Guys @ DC are not committed in any way to solve in real time our problems (just read the disclamer). Still it would be ``cool'' to be aware in time of any weirdness we might encounter before going online with our brand new Zope server full of products and stuff. Also I have a feeling DC is not soo happy to keep an online hot update of bugs and instability issues when these might compromise it to commercial parteners. So they would first like to have an inner look @ problems then announce the Zope comunity. But from our point of view, we want to know everything :-) -- CIMPOESU Teodor, Web Programmer (h) @ DIGICOM S.A.

And remember that Zope is only as stable as the OS you are running it on. If the only way you can get Zope restarted is by rebooting your OS, then I would blame the OS or possibly your OS's drivers. -- ___ // Zen (alias Stuart Bishop) Work: zen@cs.rmit.edu.au // E N Senior Systems Alchemist Play: zen@shangri-la.dropbear.id.au //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen

Err, by far my RH6.1 worked just fine, w/o blue screens :-) I don't want to make a big deal of that error cause now it works fine but IMO it was a Zope problem and I felt frustrated cause I didn't know how to track it down. So I'm looking forward for suggestions in case other [God forbid] problems show up. -- CIMPOESU Teodor, Web Programmer @ DIGICOM S.A.
