Package: samba Version: 3.6.6-3 I got internal error signal 11 and core dump in the middle of sending print jobs. The core dump error told me to look at the SAMBA3-Troubleshooting PDF. I am printing to a cups printer over JetDirect. I saw a lot of cups related printid errors as well. I have not been able to reproduce this error consistently. It happens sporadically (but often) in the middle of batches of print jobs. This is printing from a Win98 client. The exact same printing task sent again will work, so what we have been doing is cancelling the whole job on error and then resending the job.
Unfortunately I had to downgrade to 3.5.6 to get things working for now. I have the core dump I can upload if it will help to identify the issue. Tested on Debian Wheezy(testing) and later Sid, with a 2.6.38 armel kirkwood kernel.
