APAR status
Closed as program error.
Error description
Problem description: When multicast doesn't work, the app
server can not communicate with the node agent. The fix
is for the node agent to reply to a discovery message
from the appserver via both multicast and non-multicast.
This will ensure that the reply is received by the appserver
even if multicast fails.

Possible errors that are seen:
ADMC0051W: Failed to do a multicast-based process discovery,
trying discovery mbean instead...
I need to check the latest trace.log to see if it still shows:
ADMD0002E: Only multicast address is allowed to open the
multicast socket
Local fix
Recycle the nodeagent. Recylcing the appserver does not correct
