I have a i386 NetBSD box running, amongst other things, samba
from pkgsrc (samba-3.0.24nb1)

The client PCs are running some big CAD files (they
run AutoDesk and design golf courses - 1.5GB files or so)

Some of the PCs occasionally see the following error :

z:\ is not available
Not enough storage is available to process this command

When they're working on the files.  A bit of a google around
suggests that this is a smb protocol problem originating at the server.

The server is runnng the following kernel :

NetBSD 3.1 (GENERIC) #0: Tue Oct 31 04:27:07 UTC 2006 
builds@b0.netbsd.org:/home/builds/ab/netbsd-3-1-RELEASE/i386/200610302053Z-obj/home/builds/ab/netbsd-3-1-RELEASE/src/sys/arch/i386/compile/GENERIC 
i386

And has a pair of 500GB SATA disks running RAIDFrame (raid 1)
It's an unpatched (at the moment) 3.1 system.

Has anyone here seen that problem, and knows a fix?

Thanks!

Carl
