Looking at the place where the error occurred, I suspect this was
fixed by the commit after 4.4.2 is released:

https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=93f55858c6ba8b5243f5dc79808926961d78d826

So I recommend you to upgrade to 4.4.3 or higher because those
versions include the fix above.

Best reagards,
