I have seen behaviour like this with older Python versions. In addition, the Zope requests could only be killed with "kill -9". The behaviour I observed was caused by a Python bug, fixed in Python 2.3.5 and Python 2.4.1. A fatal signal triggers this bug on some operating systems (e.g. Linux 2.4 with "linuxthread"). -- Dieter _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
