FYI:
I'm using samba 2.0.6 for clearcase interoperation between Unix and NT,
and while it works
great 99% of the time, I run into a problem whenever I do a complete build
on an NT system,
which involves compiling ~1500 files. The first 1100 or so are compiled
correctly, but then the following
errors show up on the NT box:
The system cannot open the
device or file specified.
And the following errors show up in the samba log file:
[2000/01/10 17:42:48, 0] lib/doscalls.c:dos_GetWd(461)
dos_GetWd: dos_getwd call failed, errno Too many open files
........................repeated hundreds of times
..............................
[2000/01/10 17:42:48, 0] smbd/files.c:file_new(85)
ERROR! Out of file structures
.........................repeated 4 or 5 times .............................
Does anyone have any suggestions on how to get around this? I've tried
changing some of the MVFS
parameters on the NT side, but that only made it worse.
Thanks in advance for any help on this issue!
Ozzie,

The default maximum number of open files under Solaris is 1024. You can either: - crank the limit up by using ulimit before starting samba, or - crank down the number of Mnodes on both free lists (we have ours set to 800). Also: OBackus@DigArch.com said:> [vobstore] > path = /vobstore > read only = NoI would add "oplocks = False" to your config. I've also found complaints in the log file about the socket option IPTOS_LOWDELAY being unknown; you might want to remove it just to reduce your log file size. -- Don Koch koch@cognex.com ---- Not speaking for Cognex Corporation.
FYI: Bumping the open file limit to 4096 on the sbd process has taken care of the problem! Many thanks!

Use the ulimit command to do this.
