NFSKTCPD process using 100% of cpu on K460

NFSKTCPD process using 100% of cpu on K460

I have dual processor K460 that has a process NFSKTCPD that
is using 50% of the systems cpu resources. I understand this
process is initiated from a client and that it can't be killed. The
process jumps between cpu's using up all of the cpu. I have about
10 workstations(C3000,C3600,B2600) that NFS mount a RAID
partition. Everything still works ok except the system is slow.

I have installed the following patches in hopes of fixing the problem, but it didn't work. PHNE_24910,PHCO_24777,
PHKL_24255, PHKL_24551,PHKL_24569,PHKL_25728,
PHKL_25729,PHKL_25840,PHKL_25842. Also, all the special
installation instructions were followed.

This system also has 2 nic cards and when I removed the cables
and rebooted the process did not return. Then I connected the
network cables and still no process. Then I rebooted a client
workstation and boom there is the process.

As a possible work around, I have reniced the process to a low
level of 39.
I am not running NIS. Could it be a possible NFS 2 vs 3 problem?
Any suggestions.??

Thanks in advance.

Hi

Info:-
http://europe-support.external.hp.com/cki/bin/doc.pl/sid=53faedef1828c88744/screen=ckiDisplayDocument?docId=500000000092556

NFS 2 to 3 and vica versa has problems, Hp-UX 11 installs by default V3 and 10.20 V2.

Either down load V3 from the HP site or upgrade your 10.20 servers to 11.

Hi,

I forgot to mention the K460 is running HP-UX 11.11
and the workstations are running 11.0.

Hi Paula,


I'll have to check the patches on the workstations. Good idea.

hi John,

Suggest you update the NFS patches on your system. Look for ONC/NFS General Release patch in particular.

Hope this helps.

Hi all,

By some strange reason, the cpu
usage has dropped to .01 for this
process. I didn't even patch any
of the clients. I still plan to patch the
clients.
Thanks to all for your help.

John
