On the good run, I don't get any message, which is good.

On the bad run, I got the following message ...

boston kernel: nf_ct_tcp: invalid packed ignored IN= OUT=
SRC=127.0.0.1 DST=127.0.0.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=8162

This message is displayed repeatedly after the job got "stuck", once
ever 3 seconds coinciding with every 3 seconds of the print job sent.

Hope this helps.

Jeff.
