pgpool can accept new connection from psql, and can finish pgbench test without "-C" option. I also can run "-C" again without restart pgpool, but it always refused new connection after 28232 tries.
Just now I setup a new pgpool platform in our lab, we got same failure with pgbench -C. Thanks very much for your care.
