samba - Feb 2002 - Trouble with Samba 2.2.2 under HPUX (high cpu utilization)

Hello,
	I have been tracking down a cause for some abnormal CPU utilization with samba.
It appears after looking at glance plus that samba is spending the majority of
its time (like around 75-80%) doing lstat system calls.   When I used tusc I
discovered that it appears to be looking for a file /tmp/.winbindd which I am
assuming is the unix domain socket for winbind.   However this system is not
compile with winbindd as it wasnt supported under HPUX 11 in 2.2.2 and I dont
really have a need for it.   All of our unix users have identical named windows
accounts, so its of little concern to me at this moment.

	I looked into the source for references to that file and it appears that smbd
always tries winbind first regardless of whether or not its compiled to support
winbind or not.   This appears in my case to be rather heavy on system call
overhead, dealing with errors.   I think perhaps something that is aggrevating
this is the broken Visual Basic Application ont he other end is written to open
a logfile and write a line then close it to cause a sync to happen which has got
to cause alot of access checks which intern will try to resolve uids.



	Has anyone else run into problem with this?    What should I do to fix the
situation, my first thought is to comment out the winbind checks from my smbd
and recompile, but I want to see if there is another way.
