[pgpool-general: 5537] have lots of CLOSE_WAIT in pgpool 3.6.2

[Ziyun Audrey Wang]

Hello

We have upgraded to pgpool 3.6.2 (pgpool-II-pg96-3.6.2-1pgdg.rhel6.x86_64.rpm<https://arm.mo.ca.am.ericsson.se/artifactory/proj-mdn-yum-local/builds/ops/3pp/pgpool-II-pg96-3.6.2-1pgdg.rhel6.x86_64.rpm>)
And we got many CLOSE_WAIT in the pgpool node, and pgpool seems hangs (application cannot connect to DB after this)
The restart of the pgpool process will fix the CLOSE_WAIT, but then it will happened after running a while.

We don't have this problem when we use pgpool 3.5.2

Is this a old problem in new release?
Is there any fix for this?

Thanks a lot!

Best Regards
Audrey
