samba - Jul 2002 - group ids not showing and recommended kernel changes for Samba on HP-UX 11?

The Samba documentation does not mention anything about it, but I am
wondering 
if I should increase some of the tunable kernel parameters on an HP 11.00
server 
that is running Samba 2.2.5 with winbindd? I am currently using the default
kernel 
after installing from scratch and the system has 2GB memory and 4GB swap. 
It is an N4000 HP server. 

After creating some files from a Windows2000 machine to a share on the HP 
I went on the HP server and did "ls-l" and the user is correctly
populated,
but the group shows only the group id number! 

I am on a large NT domain and when I try to run "wbinfo -u" or
"wbinfo -g"
I get the following errors in log.winbindd: 

[2002/07/29 16:27:51, 0] lib/util.c:(671) 
Memory allocation error: failed to expand to 19957504 bytes
[2002/07/29 16:27:51, 0] nsswitch/winbindd_group.c:(717) 
failed to enlarge buffer! 
[2002/07/29 16:36:39, 0] lib/util.c:(671) 
Memory allocation error: failed to expand to 16504832 bytes
[2002/07/29 16:36:39, 0] nsswitch/winbindd_user.c:(570) 
failed to enlarge buffer! 


I am thinking the above errors could be fixed by increasing some of the
kernel parameters?

Thanks,
