Package: samba
Version: 2:4.20.1+dfsg-5
Severity: important
Dear Maintainer,
Since the end of March, smbd sporadically crashes with the following error:
INTERNAL ERROR: Signal 11: Segmentation fault in smbd
I´m not sure what causes this. It was working stable before and my Samba configuration hasn't changed. Hence, I suspect that the update of some package has caused this.
Please fine more details in the log snippet below.
Thanks in advance,
Timo
