TRANS2_FIND_NEXT can use a lot of open file descriptors on samba.
You'll probably need to tune the "max open files" parameter in smb.conf
to something higher, and may also need to tune the server's OS to allow
for a single process to have more open filehandles (including bumping
ulimit -n when starting smbd).
