[Zope] Zope threads on Slackware

Hi all, urgent need for help on Zope threads on Slackware linux. I'm not familiar with slackware and the sysadmin is not familiar with Python, but the situation is that somehow Zope does not run more than one thread on the system. Python is compiled with threads - and there seemed to be no errors on that. Zope is configured to start 4 threads. It looks like Zope tries to start the threads, but these threads die very fast ( in microseconds or so ). Any help on debugging would be appreciated. -huima
