I have tried with your shell script with pgpool-II CVS HEAD. Between
16:56 and 17:26, about 30k SELECTs have been executed so far. As you
can see RSS was growing from 1904 to 1912 but VSZ remained unchanged
23208. Thus I think there's no memory leaking. Pgpool-II is operated
in streaming replication mode. This is Linux kernel 2.6.27. What mode
are you operating? What platform are you using?
