samba - Oct 2007 - ERROR: too many handles (1025) on this pipe

Hi!

i'm desperate. I'm running samba 3.0.25a in a solaris 10 box and just
on  printer showed problems.
in log files i get a lot of this messages:

[2007/10/29 09:17:13.747823, 0, effective(10176, 10000), real(0, 0)]
pc_server/srv_lsa_hnd.c:(112) create_policy_hnd: ERROR: too many
handles (1025) on this pipe.

and to come back to work only stopping and starting samba service again.
This morning i setup log level 10 for the two machines that showed
problem. If needed i can attach this files.

And i've tcpdump trace file from one of those machines.

here is my smb.conf:
