I had a customer call in today they are running Win2003 with 22 gig of ram (that may be a mistype on their end, it may be 32gigs of ram).

They cranked up their postgresql max_connections to 500.

When PostgreSQL hits above 400, it dies and I don't mean a slow crawl type death. A death where all connections close and the database does a rollback and restart.

I was able to reproduce with a simple pgbench on my own win32 environment.

I wasn't able to go above 300 with mine.

Any thoughts?
