Samba 2.2.3a on Solaris 8

  We have seen the same thing, except it was fd 14.  lsof showed
this was /var/samba/locks/printing.tdb.  This was with 2.2.3a

  We tried 2.2.4-pre today.  Same thing.  System seems OK for a while.  
After a few hundred smbds running, we start seeing problems.  Many
processes all doing continuous fcntl's on printers.tdb.  (each process
doing over 100 fcntl/sec).   Some truss output is included below.
