Re: [Zope] Strange Zope behavior/Instability (Zope going down)
Jason, Rob: Ive just seen your mails, and thought uuups! One of my customers is using zope (2.1.4; ms cluster server; nt4 basis). Zope has been running fine for more than three months, but on 1st of June it crashed, and didn't came up again (no response from server even the zope services seemed to be up and running). every minute or so, we got the following message in the event-view: restarting zope. The only chance I saw to bring Zope up again, was to reinstall the whole thing, and use the backed up Data.fs file. So far so good, its now running again, all data is ok, nothing lost. But: whats the reason for this? i simply have no idea (logs didnt show anything relevant as far as i understand). why i thought uups, was because of the same time this happend to me as to you (you also use 2.1.4). could it be a problem with 2.1.4? should we consider to upgrade to 2.1.6? regards Harald - Original Message - From: "Jason Spisak" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Friday, June 02, 2000 9:15 PM Subject: Re: [Zope] Strange Zope behavior/Instability (Zope going down) > Rob Sporleder writes: > > > The shell was on my local machine... > > > > That's the same as tryinga browser for network purposes.

RE: [Zope] Strange Zope behavior/Instability (Zope going down)
The shell was on my local machine... BigBrother is the monitoring software we use. The client is installed on the same server as Zope. When viewing the log files there were no connections made by BigBrother (checking for http connections). However, there were many hits from outside IP's.

It was the command line within the shell. Actually, I've found something that's interesting... The system clock is an hour slow. The logs are written 6 hours ahead. I greped the log file for BigBrother and found an hour gap with no BigBrother entries from 06:37:53 and 07:40:23, roughly the time that the site seemed to go down.

RE: [Zope] Strange Zope behavior/Instability (Zope going down)
All of the python z2.py processes are still running. I haven't checked if I can get to it using http://localhost. The server is offsite. However, I did try an http get from the command line and it did not respond. -Original Message- From: Jason Spisak [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 31, 2000 1:13 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: [Zope] Strange Zope behavior/Instability (Zope going down) Rob Sporleder: > I received a server not responding error.
