DCE - RPC Communication Breaks on Redhat 9.0

DCE - RPC Communication Breaks on Redhat 9.0

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.

As you can see some bytes present in the UDP queue. I am not sure why rpcd
listening is not able to get this.

Any help would be appreciated.

Thanks,
