[Zope-dev] 2.6 hang problem

[Chris Withers]

Hi,

I've got a site running a CVS version of Zope taken from the 2.6 branch on 
19/9/02. The site is running off Python 2.1.3 on a Debian box and also uses ZEO 1.0.

Yesterday, it appears this site died during a ZCatalog update as the last entry 
in Z2.log was for the advanced catalog management form. However, there was no 
entry for the actual re-catalog.

Nothing was output to the console.

Very weirdly, when I went to look at the stupid_log_file, it was totally blank.
Now, I did a tail -f on that file, and when I executed the Zope stop script, the 
following were output to the stupid log file:

------
2002-10-02T10:41:55 INFO(0) Z2 Caught signal SIGTERM
------
2002-10-02T10:41:55 INFO(0) Z2 Closing all open network connections

2002-10-02T10:41:56 PROBLEM(100) Z2 A handler for SIGTERM failed!
Traceback (innermost last):
   Module zdaemon.SignalHandler, line 58, in signalHandler

   Module Signals.Signals, line 83, in closeall

   Module ZEO.zrpc, line 234, in closeIntensionally
   Module ZEO.trigger, line 90, in pull_trigger
OSError: [Errno 32] Broken pipe

When I restarted Zope, things appear to have come up fine. The funky new error 
log object is empty, but I guess it's not a persistent thing...

The storage server (also running off the same CVS version of Zope) seems to have 
survived fine through all of this.

Likewise, a Windows ZEO client running off the same Zope version seems to have 
kept going fine.

Any ideas?

cheers,

Chris
