Samba lock up under Solaris 2.5.1

[Peter Polkinghorne]

On our most heavilly loaded Samba server (running 1.9.18p10 under Solaris 
2.5.1) we have got occaisional meltdowns with load average rocketing to 100+.

The evidence indicates lots of smbd processes running.  Syslogs indicate lots 
of:

Nov 12 12:48:35 zeus.brunel.ac.uk smbd[21572]: Failed to set socket option 
SO_KE
EPALIVE
Nov 12 12:48:35 zeus.brunel.ac.uk smbd[21572]: Failed to set socket option 
TCP_N
ODELAY
Nov 12 12:48:41 zeus.brunel.ac.uk smbd[21573]: Failed to set socket option 
SO_KE
EPALIVE
Nov 12 12:48:41 zeus.brunel.ac.uk smbd[21573]: Failed to set socket option 
TCP_N
ODELAY

Also on the most recent incidence (happening once or twice a week), it was 
reportedhed that there were a lot of smbd connections bound to socket *.139 in 
the idle state.

A glance at the source code indicates such failures ignored.

Has anyone else experienced this?

What more should I do to diagnose?

Thanks,
