[Samba] 4.4.8 - There is not enough space on ...

[Jeffrey Johnson]

I recently upgrade an older version of Samba (3.x) to a less older version
of Samba (4.4.8) and now have users reporting the following error.

There is not enough disk space on home (servername).  You need an
additional XXX to copy these files.

I see some older posts referring to adjusting, *min receivefile size = *
*0, *however I do not have this set and the default is 0.

I don't see anything in the log files to point me at anything, if have
checked to make sure quotas are turned off

# quota -v user
Disk quotas for user (uid 1001):

Any help would be greatly appreciated.
