This also sort of sounds like maybe a job using shared memory got :ABORTJOB-ed,
and so the shared memory wasn't cleaned up, which causes problems for Samba
when trying to reuse the same shm id.

Always do a controlled shutdown of programs using shared memory or semaphores,
else you will need to learn how to use IPCS and IPCRM to clean up the mess left
behind by :ABORTJOB (or any other form of abnormal termination).
