Hi,

could you send the real smb.conf, since RTF encoded testparm output is 
bit clumsy to read...?

I read in the testparm dump that you are in 'security=server' mode. Do 
you really need it? Does your server participate in a domain? 2.2.8a can 
happily participate in a NT4 or an NT4 compat on ADS domain.

And could you check with Sam the limits of the HP-UX kernel (number of 
processes for the system, by user, max number of open files, etc.)?

I'll check tomorrow on HP-UX server at work what kernel parameters could 
  hit Samba.

Could you also set 'log level=' to a bit more than 1 to see more output 
in the logs? That would help.

Regards,

J.
