If the RFI is causing one of the ethernet controllers to fault, it
could be that after the fault clears the network stack restarts all
the sessions. Windows can get very "chatty" on the network when it is
first coming up with lots of broadcasts. I can imagine your networking
stack and ethernet driver getting very busy and causing a spike in
DPCs.

What I just said is pure speculation. You might try repeating the
experiment while watching DPCs and which processes get the CPU time.
