Dear Maintainer,
* What led up to the situation?
Enabled aio_pthread.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Access by a Mac OS client seems to crash smbd from time to time.
* What was the outcome of this action?
* What outcome did you expect instead?
A backtrace of the crash follows:
Core was generated by `/usr/sbin/smbd --foreground --no-process-group'.
Program terminated with signal SIGABRT, Aborted.
