Обсуждение: BUG #1365: Loose connection in idle mode

The following bug has been logged online:

Bug reference:      1365
Logged by:          Jean Claude
Email address:      gaudetjc@neuf.fr
PostgreSQL version: 8.0
Operating system:   W2K
Description:        Loose connection in idle mode
Details:

I didn't found any related topic about timeout connection with a non
activity of clients. In fact the server disconnect any client after ~10
minutes of inactivity. I try it with my program that i am developping, psql
and pgadmin III. All do the same after arround 10 minutes with inactivity
or
idle, the server diconnect by logging a message "unexpected EOF on client
connection".
Hoping to find out the reason or maybe a bug but all my project is in
standby now to fix this problem.
Thanks in advance for all your help

There is no disconnect timeout in Postgres.

This sort of thing has been reported before, and it's always been due to
overaggressive dropping of idle connections by a firewall in between the
clients and server.  NAT routers have to keep per-connection state about
the address mapping, and they will drop that state after some period of
no traffic.  10 minutes seems unreasonably short though.  I hope it's
configurable on your box.  If not, you can either buy a more reasonably
designed router, or tweak your clients so they do something at least
once every few minutes...
