*snip Tom's reply*
I have a situation vaguely related to this.
At some point Postgres was not shut down properly and now everytime at
startup I the error log gets something like:

---------
root% tail -f errlog
Waiting for postmaster starting up...DEBUG:  Data Base System is starting
up at Sat Nov 25 16:53:10 2000
DEBUG:  Data Base System was interrupted being in production at Sat Nov
25 16:35:27 2000
DEBUG:  Data Base System is in production state at Sat Nov 25 16:53:10
2000
FATAL 1:  ReleaseLruFile: No open files available to be closed
............................................................pg_ctl:
postmaster does not start up
---------

After that, all postgres processes die and the cycle begins again on
subsequent attempts to start postgres.
At one point I would receive some "Too many open files" (or similar)
error with postgres holding more than 750 file descriptors -- almost
entirely consisting of socket streams.
What is the significance of "ReleaseLruFile" and how can I repair this?

This is using FreeBSD 4.1-RELEASE and Postgres 7.0.2.

Thanks
