Is it possible that someone was causing other IP traffic to VM at the
same time. If you are using Guest Sharing, I don't believe that the
communications protocol is over IP (it isn't SNA either). The fact that
you are seeing high TCPIP CPU utilization may just be a coincidence.

Can someone give me an idea what could have TCPIP been doing by running
at 60% of the CPU time?
A VSE/ESA (2.7) batch job intiated a mass deletion to a DB2 (7.2) under
z/VM 4.4 by scanning a large table, selectively delete records by date.
DB2/VM was running 30%, but TCPIP/VM was running 40-60%. I am not a DB2
guru, but I suppose it SNA traffic and there is no network
communications, what is TCPIP doing? Please advice where do look.
Thanks.
