Hey Guys

I am trying to increase the max_connection from 100 to 5000. I modified shared_buffer and changed kernel parameters according to
http://www.postgresql.org/docs/9.2/static/kernel-resources.html#SYSVIPC.
When i stress test it with 500 concurrent request, then after 150 - 160 concurrent connections my database enters into recovery mode and it fails the request. For my stress test i am trying to get data from one table.
Do you guys have any idea what is causing the problem or if i am missing some other configuration?
