I don't know what verison of pgpool you are using nor your pgpool.conf
but I guess your clients are just sloppy in that disconnect the
connection without using disconnect API (what kind of language are
using for the API, by the way?)

In this case you will get errors such as "unexpected EOF on
client connection" from PostgreSQL even if you don't use pgpool
anyway.
