[Zope] zwatchdog dead

[jb]

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,
