Hi all,
can any help with our strong problem:
we are using Samba on Linux as fileserver for Win2k clients running CAD software
"Solid Edge". This program opens many files and on big projects freeze.
We tried configuration:
- samba 2.2.3a or 2.2.4
- RH 7.2 or 7.3; kernel 2.4.18, 2.4.19 up to -pre10-ac2
- i686/1GHz CPU, 512 MB RAM
- "/proc/sys/fs/file-max" from default 8192 up to 20000 or 30000,
- smb.conf "max open files" from default 10000 to 20000 or 30000 or for debugiing to
1000
- when I periodically test "/proc/sys/fs/file-nr", then number of used file handles is
always less than 150, but number of allocated file handles is any time near
same
(about 500), but then start quick increased and stop on slightly more than
value
"max open files" from "smb.conf"
- when I set debugging in smb.conf, in station log is suspicious record about closing
file with filedescriptor fd=-1 :

- its all, sorry for long log listing.
I'm not familiar with C and not know internal mechanism in samba and OS.
It is bug in my "smb.conf", smbd daemon, Linux OS or Win2k client?
Or can any advise me on next progress?
Thanks in advance,
Frantisek Hanzlik
