Thread: Postgresql server "crash" after some day

Is it possible that you're application is not closing connections, and
the server has a limit on connection count, and that is reached in a few
days ? Actually I'm not sure if the "max_connections" parameter is
applicable to local connections too, cause in that case you shouldn't be
able to connect locally either...

Just a thought.

Cheers,
Csaba.

after some day? If you did not change the config files and if there
was not another process using that port during the start, chances
are you configured a firewall which just refuses connections to port
5432?

You've suppressed the part of that message that's actually useful ---
what was the kernel error message exactly?

I'm betting it's a firewall kind of problem.  What is between your
remote host and the database server?
