You probably did not tune nflocks for Samba. The default kernel variable will be exhausted quickly with Samba due to the extensive tdb locking.

As long as you are doing nflocks, you might as well do the other stuff too:

 nflocks
 (10*maximum smbd)+(other apps + system)
 example 1000 connected clients and baseline NFS system
 (10*1000)+(2048) = 12048

 nfile
 ((23+opens_per_smbd)*maximum smbd)+(other apps+system))
 example 1000 connected clients and baseline NFS system
 ((23+7)*1000)+(8192)=38192

 nproc
 (maximum smbd)+(other apps+system)
 example 1000 connected clients and baseline NFS system
 (1000)+(1024)=2024
