Package: samba Version: 2:4.12.5+dfsg-3 Severity: normal Tags: upstream X-Debbugs-Cc: josep.m.pe...@gmail.com
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. #0 0x00007fc960969cb1 in __clear_internal_signals (set=<optimized out>) at ../sysdeps/unix/sysv/linux/internal-signals.h:74 74 ../sysdeps/unix/sysv/linux/internal-signals.h: No such file or directory.

# # Sample configuration file for the Samba suite for Debian GNU/Linux. # # # This is the main Samba configuration file.
