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.
