Comment added by Karl Wright:

It's been a while since this was done with the ManifoldCF code base, but the MetaCarta code
base on which it is built regularly crawls 5 million or more without any issues of this kind. 
So the possibilities are:

(1) Misconfiguration of PostgreSQL

(2) Something about PostgreSQL 9.x.

(3) Something broken in the ManifoldCF code that got broken sometime in the last few months.\\

The obvious cross-check is for someone else (probably me) to do a large crawl while using
a properly configured PostgreSQL 8.x, and see where that leads.  Unfortunately I
probably won't have time to do that until next week, unless I can squeeze in a few moments
tonight.\\ \\

In reply to a comment by Farzad:
Using the default Null Output and File System connectors for this test.  I'm running on an
8 processor system, 8 GB of RAM, with 10,000 RPM drives.

So I seem to be in a pickle, cause I have 30 worker threads, and 400 allowed db connections,
I'm getting this error.  I'm going to set the db back down to 100 and see what happens.

I uploaded my configs to in case I over looked something.

Oh, the other thing, this happens around doc count of 60,000.  Have you tested with a very
large test set, perhaps 250,000 or 500,000?
