Well, this sounds familiar to me. Which version of pgpool-II are you using?
We got those CLOSE_WAIT's too during stress tests on our php framework.
They are gone since the last version 3.1.3. I assume it got something to 
do with a syslog issue.
May you try log_destination = 'stderr' in your pgpool.conf just to 
clarify if this is the case.

>> Hi,
>>      I have been using PgPool-II for my postgres DBs on the Amazon EC2 instances. However, I have been experiencing some issues. After a certain period of time, it no longer allows new connections from clients / application to the PgPool. It seems to get stuck in a TCP CLOSE_WAIT session. This basically accumulates to alot more which then disallows any further connections to the PgPool.
>> So at one point I had to temporarily set all connections directly to Postgres. The issue is resolved by restarting PgPool. Then after a certain period of time, it happens again, then another restart of Pgpool is required.
>> Can someone advise me how can I solve this?
