Have you investigated the possibility that Samba legitimately needs more
filehandles than that?  Even if there are only 4 clients, they may be
opening 2000 files each (The output of smbstatus right before the system
exhausted its filehandles would be interesting)  If that's the case, you
can update the amount of available filehandles using sysctl or by
recompiling your kernel.

We have some PostgreSQL servers that require the filehandle limit be raised
to 50000, for example.
