[linux-cifs-client] cifs client problems

[Gorazd Golob]

Hello!

I'm writting about problems with connectivity of linux client with very
intense read activity on mounted w2k share (over cifs). Below is attached
kernel log .. problem like it looks like is in java binary (jserv is
running this "read operations"), but it has something to do with cifs.

configuration:
Linux 2.6.10-rc2 (cifs tree - 11/24/2003)
Slackware 10.0
Glibc 2.3.2
cifs mounted to w2k server


Any ideas ? Thanks, Gorazd.
