"see logs"

Look at your proxool logs and see why the connection was closed. The
error message its self gives you the next step.

I suggest reading this:
   http://wiki.postgresql.org/wiki/Guide_to_reporting_problems
for some hints in case you need to ask a more detailed follow-up.

Without some idea of why the connection was "automatically closed by Proxool"
there's likely little we can do to help. If PostgreSQL is to blame, there's
probably useful information about the problem in your PostgreSQL logs. The
logging documentation might be useful to you here.
