We have a couple of these in the error log.

This one generated multiple alerts per day...there is a message queued up on osfkarl10 trying to go out.

To shut up Nagios, I moved that message to osfkarl12:~/tmp/

Sorry, busy week. Will be able to look at this and other bugs tomorrow.

Per the comment, the message causing this was moved to osfkarl12:~/tmp
