Issue/Introduction

Our network administrators are asking why is xFlow attempting to allocate high port values.  An example entry in the incidentMS.log shows attempts to access port 57845:

WARN - 20XX-XX-XX 16:12:29 [akka.cluster.Cluster] - Cluster Node [akka://[email protected]OM:57845] - Couldn't join seed nodes after [3134] attempts, will try again. seed-nodes=[akka.tcp://[email protected]OM:2551, akka.tcp://[email protected]:2551]

Environment

Release : 17.3

CA Service Management - xFlow

Resolution

play framework which is responsible for xFlow is been upgraded to latest version to remediate vulnerabilities..

As part of this upgrade port 2552 which was used for cluster management is been upgraded to 25520 (From Play Framework itself).

the high numbered port numbers(25520...) are from the playframe work itself which cannot be configurable.
