Issue/Introduction
Error Message :
U02000100 Non-encrypted message of 'n.n.n.n:m' will not be processed.
The Agent doesn’t recognize the Event Monitor as a trusted communication partner. Even though the connection is established for a local / own IP address.
A solution for this issue is to add the IP address to the “Trustable IP-Addresses” file in the Agent object. However, this causes the Agent to crash with S0C4 errors:
U02000100 Non-encrypted message of 'n.n.n.n:m' will not be processed.
When using z/OS the connection from the Event Monitor to the Agent fails and the above error message is displayed.
Investigation
When an Event Monitor is started it connects to the Agent, but the Agent rejects the connection and errors similar to these appear:
20160818/121329.608 - U02002039 Successfully established connection with '10.0.0.152:49431' (socket handle = '1').20160818/121329.609 - U02000100 Non-encrypted message of '10.0.0.152:49431' will not be processed.20160818/121339.609 - U02002040 Disconnected from '10.0.0.152:49431' (socket handle = '1(ID=6)').
The Agent doesn’t recognize the Event Monitor as a trusted communication partner. Even though the connection is established for a local / own IP address.
A solution for this issue is to add the IP address to the “Trustable IP-Addresses” file in the Agent object. However, this causes the Agent to crash with S0C4 errors:

Cause
Processing exstartq trusted IP list causes agent crash. Eventmonitor visitcard socket is not accepted as trusted socket. That causes repeated unsuccesful EM connection in case IP address discovery doesn't provide IPs of other LPARs.
