Hi. I've noticed huge decrease in performance. During this in htop i see a lot (200 - 300) of connections in state "startup", each of them eats 3-3% of CPU time. This processes are not visible in pg_stat_activity so i cant understand what they are doing, and i cant kill them. I cant see the bottleneck in Disk IO to. The logs of postgres says nothing to. I am confused..... What can be the cause of huge amount of "startup" connections.... Maybe its better to start use connection pooler such as pgbouncer? Thanks a lot.
PS. Server config is: 2 * Intel Xeon 2660 CPU with 64 gigs of RAM. Hardware RAID10. Centos 6.6, PostgreSQL 9.1.2
