I really can't see that is possible file-max is set to 838860. I believe
it is based on the amount of ram on the machine and we have 8GB. ulimit
-a reports you can have 1024 open files. I thought maybe we were running
out of descriptors for the postgres user but that should not bring down
the machine. Thoughts anyone.
