Another oops in 2.2.14

Hi,

I am experiencing some strange oopses in the kernel
after upgrading three x-terminal servers from 2.0.36 to 2.2.14.

* System information:

Dual Pentium II, running RedHat 6.0.
The kernel is patched with the patch: patch-2.2.14-nfsv2
Both kernel and the patch is fetched from the CVS repository.

Primary task for this machine (and the others that oopsed) is
serving about 20 other machines whith X. Due to heavy use from
at least 20 users (and more counting remote users) we also had
to increase the NR_TASKS in /usr/src/linux/include/tasks.h to 2048.
Another trick we had to apply was
       print 8192 > /proc/sys/fs/file-max
       print 32768 > /proc/sys/fs/inode-max 
In 2.0.X kernels we applied 
       print 3072 > /proc/sys/kernel/file-max
       print 9216 > /proc/sys/kernel/inode-max 

This is probably not connected to the oops, and maybe something I
have not grasped, but what has happend to the 2.2.x kernels 
demanding so many open files/inodes compared to the old 2.0.x?

Now we are running 2.2.10 and 2.2.13 kernels due to the problems
we have with 2.2.14. We really would like to use 2.2.14 due
to the many fixes useful to us, so I hope that someone will take
a look at this. 

Here goes:

The machine freezes after this and has to be booted whith the button...
I have some more oopses as well, if needed.

Any ideas anyone?
