Can't set DBI::db=HASH(0x8b3efb0)->{PrintWarm}

[Daniel M.]

Upgraded to 4.4.0 and now I see the following in the log:

RT is acting normally but these warnings keep on appearing in the logs.  Not sure what to make of it.
I want to make sure I clean this up before continuing with my configuration as I have a "separate/relay" mailserver.
