All,
  Since upgrading to 1.4.2, I'm having seemingly random 
failures of our main ldappc provisioning. The initial run goes 
fine, but then once it starts running the intervals, I can 
never predict how long it will go. Sometimes it runs for hours 
(interval is 15 minutes), sometimes it dies after just a few 
intervals. It rarely lasts more than a day, though.

I have logging cranked up, but the debug log doesn't give any 
more than the following when it fails:

During successful intervals, the logs typically have 
GroupEntrySynchronizer messages between the Started & Stopped 
lines. Since I'm not seeing those when it fails, it seems like 
it may be something during the initialization of the interval 
run. The database isn't changing between the last success and 
the failure, so I don't think it's something in the data. Any 
pointers for what to look for would be great.

In other news, the slowness I was seeing in initial 
provisioning runs is gone now. A combination of moving to 1.4.2 
& giving grouper a dedicated ldap server to talk to. Now the 
initial provisioning takes around 2 hours (down from 30+).
