The program is running. Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]

Got lot of the same errors on various files

[Chuck Short (zulcss)]

Can you provide the output of testparm -S /etc/samba/smb.conf and install the samba-dbg package and run the command /usr/lib/debug/usr/sbin/samba -F

Thanks
chuck

I have a similar stack trace maybe related to this, happens often a network user tries to access a network device, he got the windows messages that the network share is not available, smbd crashes and after that, the user can access the network share. But from time to time, the crash continues and only a complee restart of samba has to be done.

comment from upstream:

"Quick shot -- do you have something like SELinux or so running? If yes, can you
try disabling it?
"
could somebody try that and report back? thanks in advance.

[alessandro (asandini)]

No, no SELinux here.

If it can help, I noticed that the crashes only happens in shares where
"force group" is used (and never in the homes directories)

Looks like a dup of bug #216358.
