[pgpool-general: 6252] forked new pcp worker followed by exit - all day long

[Alexander Dorogensky]

I'm using pgpool-II 3.6.10, postgres 9.6 and
4 app nodes (with pgpool, each node connected to the other 3)
and 2 primary/standby db nodes in streaming replication.

Below is the output from pgpool.log on one of the nodes.. It doesn't look
normal to me.. is it?
