What are your OS shared memory settings ? e.g. shmmax and shmall

shmmax = 134217728
shmall = 4294967296

And postgres shared_buffers ? (I'm not sure this matters but I'm curious)

Don't know about shared_buffers. How do I look that up?

And approximately how many memberships do you have ?

I can do that.  What resource exactly?  Is it max_locks_per_transaction?
I know I've created larger groups than this.  And I think I've deleted them.
What takes so much space?

It looks like this is the problem (different than last time?)  Can you give
more resources to the DB?

Fyi, I changed the Grouper DB layer so it logs the nextException for
postgres, and sent Jim a build, hopefully we will see the root problem.
 Will keep you posted...

Ran with the new grouper.jar.

The event log is attached.
