I recently patched my Solaris server and suddenly my Samba service is not
working correctly.
When Anyone accesses a samba share the samba daemon panics and shuts down.
Solaris than restarts the system, unless there are multiple panics
simultaneously than the service is placed in maintenance mode.
The SAMBA server is a stand alone supporting a dozen end users for a large file
store behind the covers.
I am at a loss at what is causing the problem.
Searches indicated a potential issue with printing so I added the section to
comment turn that off. Befroe that the log was filled with comments about cups
printing not being available.
Thank you in advance.
