samba - Sep 2000 - Out of file structures

Hi all,


does anybody knows about the following Error ?!??!


[2000/09/25 17:40:55, 0] smbd/files.c:file_new(85)
  ERROR! Out of file structures

seems to be the max open files problem, am I right ?

We did a research in some news and usergroups and in some answers 
it was mentioned, to compile samba with the sfio package to avoid using
the select(3).
Is that right ? Does anybody has any experiences with this ? Has anybody
compiled samba with
sfio? If yes, how ?

We are running Samba 2.0.7 on a Solaris Cluster with Solaris 2.6 and
Clearcase v4.0

any ideas ?

awaiting the community answers ;)

best regards ....

According to Google your questions/answers ratio on newsgroups and
mailing lists appears to be NaN.  Not that this is unusual,
unfortunately, it's the classic tragedy of the commons, but I just
thought I'd point it out. (:

I'm running Samba version 1.9.18p10 on a Solaris 2.6 server and have started
to
receive the following error when users attempt to access autodesk/Inventor (CAD)
assemblies that are stored on the Samba Server. The users are using NT 4.0.

ERROR! Out of file structures - perhaps increase MAX_OPEN_FILES?


What is causing this and what can I do to fix or work around the issue?

Hi Bob,
means pretty much what it says; each client attaches to its own smbd
process, and in *nix, there is a kernel parameter that determines the
maximum number of files that a single process can have open simultaneously;
so if the user has a LOT of files open, they could reach this limit.
Depending on your kernel, this may be tuneable (ie you could change and
regen your kernel for a large max_open_files size);  but before you do this,
you should probably make sure that the user really VALIDly has that many
files open.  I have seen instances where you can get this error because some
windows clients when they get an oplock open on a file, they don't bother
closing it - thus you end up with many more files 'open' than is
necessary.
You can test to see if the oplock thing is causing you grief by adding the
parameter 
oplocks = no

I don't know what the kernel default is for max_open_files per process on a
Solaris 2.6 system - anyone on the list know?

Hope this helps,
Don
