I am puzzled about the Samba 3.4 max files limit (I am seeing it at
1014 opens) and seems
strange that dbench would open so many files, but with counters in
cifs_open and cifs_close - I see 1014 more opens than closes (from the vfs)
which matches what I see at the SMB level and what I see in Samba server.
dbench 4 fails even faster.   This also fails on other OS (opensuse,
Ubuntu etc.),
but worked on Samba 3.0.28.  Is it possible that Samba 3.4 changed their
max open file limit?
