Issue/Introduction

APMIA agent unable to bind to port 51914.

The apmccctrl.log shows following error:

ERROR 7364 [main] --- com.ca.apm.acc.controller.core.Discover  : Failed to bind on port 51914

java.net.BindException: Address already in use: bind

Resolution

During latest set of test it looks like, Agent Controller is able to use port 51914. Based on this it seems like problem may be related to environment which may be causing the port to be not free for use.

Power Shell command can be used to check if port is in use or not:
