I encountered the same bug today.
When a client (Windows or Mac) connects to the samba server at some point in
time (not clearly reproducible, I guess file access or directory listing) the
'panic action' script is executed with the same output as above. The log file
tells me:
[2011/11/18
[Expired for samba (Ubuntu) because there has been no activity for 60
days.]
** Changed in: samba (Ubuntu)
Status: Incomplete = Expired
