Re: [Samba] Samba 4.9.3 and the "10 hour problem"




Hmm…

I see that there is a patch in the bugzilla page for that bug. I guess I could try that one… :-)

I notice in the patch that there is a lot of talk about SMB2 - we use SMB3 mostly now. But perhaps there is some code sharing? Or perhaps SMB2 is used when talking to the AD servers? Or the few SMB2-talking clients causes the problem for all of the other users? When testing the “timeout” issue I typically try a simple:

	smbclient -m SMB3 -U $USER -k //$SERVER/$SHARE
