[Zope] zwatchdog dead

Well here it is, I have installed, uninstalled, reinstalled, upgraded, and re-upgraded Zope more that 25 times in the last 2 weeks. When I get Zope 2.1.6 installed and running and upgrade using rpms to Zope 2.2.2 the server goes down and comes back up witout a problem. But as soon as I manually restart the server, this error occurs: zope status zwatchdog dead but pid file exists zserver is stopped So I kill everything, and delete the pids and locks /var/run/zwatchdog.pid /var/lock/subsys/zope And I must be an idiot, so somebody help me out here. What's going on? Thanks, johnb
