DCSV9415W: Received packet larger than configured buffer length 1195986768 from RMM address /x.x.x.x. Exception is <null>. This message keeps repeating in the SystemOut.log file.
A port conflict with the DCS_UNICAST_ADDRESS end point of a server can cause this issue.
Diagnosing the problem
- Check the serverindex.xml file (for the node matching the IP address mentioned in the DCSV9415W message) for port conflicts.
The port defined in the DCS_UNICAST_ADDRESS end point for each server should not conflict with the port of other servers on the same node, even if the server is not currently running.
- Check the ephemeral port range of the machines. The DCS_UNICAST_ADDRESS end point should not be using a port from the ephemeral range.
Resolving the problem
Correct any port conflict for the DCS_UNICAST_ADDRESS end point. Change the DCS_UNICAST_ADDRESS port if it is defined in the ephemeral port range.
Note: After making above configuration changes and restarting the cell, if you still see above messages then please open PMR with WebSphere Support to further debug the issue.
