[Ocfs2-users] Problems with descriptions.

[Vasyl S. Kostroma]

Hi guys!
I can’t find an answer in google, so my last hope is this mailing list.

Story.
I have two servers with same arrays. Servers connected by DRBD.
I used ocfs2 as file system, also I used NFS4 to access to the 
ocfs2 drive. I do not have any idea, but the allocated descriptors in
/proc/sys/fs/file-nr increasing every time while drive accessed.
So after some time allocated descriptions over max value and all
processes make error “To much opened files” (something like
this). I do not see any error messages in log files... Any idea?
I haven’t sleep two days 

Thank you all in advance.

Configs:
cat /etc/drbd.conf
# You can find an example in  /usr/share/doc/drbd.../drbd.conf.example

include "drbd.d/global_common.conf";
include "drbd.d/*.res";
