[Bug 1793480] Re: Panic or segfault in Samba

[Andreas Hasenack]

Thanks for the logs.

Your server seems to be out of memory. Your log.smbd.1.gz is full of errors like these:
...
   #10 /usr/sbin/smbd(_start+0x29) [0x56330c19b199]

Or something else is preventing the fork() from succeeding. You could
check dmesg from around that time, if it's still available, to see if
the kernel logged something extra about these events.
