Обсуждение: Postgresql 9 connection problem

I have very strange problem with my application, upon occasions I get following error when connecting to postgres. This happens without any pattern, often happens when I run some extensive tests in my application.

Unable to connect to PostgreSQL server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

Postgres logs shows no abnormalities. Moreover, I can easily connect to the psql console and execute query at that period.

My Postgres is 9.0.1, running on CentOS 5.

Any hints ?

Curious.  What about the kernel log, is there anything there?
