Well, you can try switching to urandom, see http://stackoverflow.com/questions/137212/how-to-solve-performance-problem-with-java-securerandom , second answer.

Just a wild guess, but did you check your random source? We had similar problems in Oracle and had to switch to /dev/urandom. It can be done with a system variable setting.

Hi Tom,

this is the entry from pg_hba.conf

host all all 0.0.0.0/0 md5

i needed to restart postgres service to be able to accept new connection, witch it strange becouse there was no load on the server and it head a lot of free ram.
