This is bug #6837 - "Too many open files" when trying to access large
number of files

I've fixed it in master and 3.5.0, and am waiting for it to be
back ported for 3.4.4.

In the meantime you can set:

"max open files = 16404"

in the [global] section of your smb.conf and this will fix
the problem.
