Do these PIDs you're seeing match the ones that the master daemon is
blowing up on?  I don't know how they'd be related but it's another
data point.

You might want to see if this fix to the master daemon's error
handling helps you out.  (apply to daemons/master.c) It's for a
problem I ran across last week and could result in the master failing
to note a new process's location.  That could certainly lead to the
above messages and maybe the other problem you're seeing.

(This fix will be in 3.1.6)
