Have you asked the Response Center to analyze your dump?

What is original panic if my cases? tcp_rput or spinlock_usav?

I would assume it was the NaT fault in tcp_rput, the other traps are normal.
You should make sure your patches are up to date.

Dennis,

> Panic string : SafetyTimer expired

Does that not imply a Serviceguard panic?

vpar, is this system part of a Serviceguard cluster?

Yes. But did that cause the NaT fault or the other way around?
