Hi All,
I have done some more investigation on this and have reached to a conclusion that rpcd daemon running on port 135 is being contacted through UDP communication but somehow it is not able to receive it.

Any help would be appreciated.

You are using the original RH9 kernel. I don't know how to deal with
the problem you've partly described, but the first thing to try is getting
all the updates, including the latest kernel, version 2.4.20-43.9.
