Hi, some days ago i sent a mail regarding a small samba installation with periodically dying nmbds. Since the customer didn't call again regarding these problems I had the opinion that everything is fine .... Today the customer called and mentioned that there are additional problems. He had fixed the nmbd problem everyday by rebooting .... :-) Now the smbds also start to die. Again no pattern. No way to reproduce. But there were strange entries in the logs linux smbd[8311]: smbd/oplock.c process_local_message(418) linux smbd[8311]: process localmessage: unknown UDP message command code (e393) ignoring with different command codes i.e. 1e73, 2b94 and others. After some of these messages have arrived the smbd processes start to panic with internal errors. one after the other. I could locate the machine which is sending the UDP messages. And we will check what happens when that machine is down tomorrow. But anyway, does anyone has a clue what these unknown UDP message codes may be?
