Hi, I've sent this message yesterday to the EuroZope list but got not conclusive answer: The eurozope.org Zope instance was down again this morning due to the same recurring problem as last week: 2001-10-18T02:32:52 ERROR(200) ZServer uncaptured python exception, closing channel <select-trigger (pipe) at 81e28c4> (exceptions.OSError:[Errno 11] Resource temporarily unavailable [/home/eurozope/Zope-2.4.1-linux2-x86/lib/python2.1/asyncore.py|poll|95] [/home/eurozope/Zope-2.4.1-linux2-x86/lib/python2.1/asyncore.py|handle_read_event|383] [/home/eurozope/Zope-2.4.1-linux2-x86/ZServer/medusa/thread/select_trigger.py|handle_read|77] [/home/eurozope/Zope-2.4.1-linux2-x86/lib/python2.1/asyncore.py|recv|335] [/home/eurozope/Zope-2.4.1-linux2-x86/lib/python2.1/asyncore.py|recv|517]) Notes: OS = Linux 2.2.19. start file = ------------------------------------------------------------------------------ #! /bin/sh reldir=`dirname $0` INST_HOME=`cd $reldir; pwd` export INST_HOME STUPID_LOG_FILE=$INST_HOME/var/stupid_log_file.log export STUPID_LOG_FILE exec /home/eurozope/Zope-2.4.1-linux2-x86/bin/python \ $INST_HOME/z2.py \ -l /dev/null -P8400 "$@" ------------------------------------------------------------------------------ (The bug happens even without '-l /dev/null').

It just happens *sometimes* (not once in 6 months, then twice in one week) on the live server. Does anyone here know what's going on ? It seems to me that this bug has been around for more than a year. Regards, S. -- Stéfane Fermigier, Tel: +33 (0)6 63 04 12 77 (mobile). http://nuxeo.com/ & http://portalux.com/ & http://aful.org/
