Hi Sujay, this looks like a problem we had with this kernel. General
advice is to move to a recent kernel. See the thread at
http://marc.info/?t=123749011300001&r=1&w=2.
nfsv4@xxxxxxxxxxxxx is the best place to report problems w/ the linux
client.

Hi,
I am not sure this is a right mailing list to report the errors
regarding NFsv4 client. I am running Centos 5.3 NFSv4 client against
Solaris 10 (x86 64 bit architecture) NFS server. I received following
coredump while running iozone benchmark for 2GB file size. I got this
error in single client as well as multiple client scenario. After the
initial dump, machine is extremely slow and I can see keyboard input
after a minute.
Here are the details of machine configuration:
Distribution : Centos 5.3
kernel version : 2.6.18-128.el5
Here is the dump :

Is this the known issue and fixed in later kernel versions ?
Thank you.
