You don't mention what OS you are running - that is always a very good idea. The is an NFS patch that addresses this problem. For 11.0, it's PHNE_25484. Look for superceded patches or equivalent patches for other OS versions.
If it ain't broke, I can fix that.

Hi Yates:

This error comes from a NFS mount request (may be an NFS hung operation due to many lock operations). If you are using HP-UX 11.00, then apply the patch - PHNE_25484 (s700_800 11.00 ONC/NFS General Release/Performance Patch).

HTH,

It is on both 11.0 and 11.i servers. The 11.i server have just been recently been patched with the March 2002 bundles.

It's a reverse port binding function call (the bindresvport) in the kernel. I think you're getting the message because the system could not find a free port after it goes through a multiple loop of the range the port that were defined ( the range is between 512->1023 ).

Basically your system is out of reserved ports. And these ..
- AutoFS
- rpc.lockd)
- NFS client
are the 3 possible components that will be requesting for the ports but couldn't get it.

Your action plan is ..
1) If it does not show up frequently it's ok to ignore it.
2) If you sees it too often then you need to identify identify all of the reserved ports (maybe use lsof) and find out is there is any other application on your server is using these ports.

Hi Yates:

These patches were released on April 2002. However, in HP-UX 11i the problem has been fixed. These are the NFS patches that released:

11.00 - PHNE_25484
11.11 - PHNE_25625

Hi S.K,

Can you please let me know how the problem can be solved if the ports in the range 512-1023 are used by another services running on the system? I am also facing the same problem and we could see that none of the ports is free in the range 512-1023.

I will appreciate your response in this regard.

Thanks,
