[Samba] Too many opened files....samba 3.0.28a

An XP client is having an issue with my 3.0.28a server. They do not have this problem on a native w2003 file server with the same amount of data.


[2008/08/20 13:25:14, 5] smbd/dir.c:OpenDir(1079)
OpenDir: Can't open DowningShotgun/DowningTest/DowningTest.files/sample. Too many open files
[2008/08/20 13:25:14, 3] smbd/filename.c:scan_directory(586)
scan dir didn't open dir [DowningShotgun/DowningTest/DowningTest.files/sample]
[2008/08/20 13:25:14, 3] smbd/error.c:error_packet_set(106)
error packet at smbd/nttrans.c(649) cmd=162 (SMBntcreateX) NT_STATUS_TOO_MANY_OPENED_FILES

I adjusted the "max open files" parameter in smb.conf to 1,000,000 files:

max open files = 1000000


Let me ask you this...is this max count tied to each smbd process or is this an aggregate number bound to all smbd processes?

It depends on your OS. This is likely an OS message. Check Google --
this is a pretty common message.

Ok, take a look inside /proc for all the existing smbd
processes and see if any of them have an outrageous
number of open file descriptors.

Ok. I matched /proc/sys/fs/file-max (i.e 1,000,000) to the "max open files" parameter in smb.conf.

This did the trick.

Apparently an application on a CIFS client (running WINXP) opens many, manyfiles.

I appreciate your help.

Thanks,
bp

I had this problem also with a rogue XP client and Microsloth Outlook.
Fixed by upgrading to 3.0.29 without altering any file system parameters.

I do not know what the default max open files param is but I do not have
that set in my smb.conf, and cat /proc/sys/fs/file-max yields 50776.

This is on a Fedora 3 machine 2.6.12-2.3.legacy_FC3smp #1 SMP Sun Feb 19
08:53:09 EST 2006 i686 i686 i386 GNU/Linux that has a pretty long uptime
06:26:47 up 228 days, 22:43, 1 user, load average: 0.18, 0.06, 0.01

Cheers,

Ray
