After installing a new version of paci_im package in scope of OA update or upgrade, OACI Instance Manager service does not start. The following message is recorded in /var/log/pa/vps.log:

2017-08-31 15:27:55,571 () ERROR JMSModule [main] - Failed to create embedded ActiveMQ broker Failed to bind to server socket: tcp:// due to: Address already in use (Bind failed)

Instance Manager node has paci_im and paci_mq packages installed.


paci_mq package is obsolete since OA 7.0 and should not exist on the Instance Manager node. The dependency on paci_im package remained since 6.0, and this is recognized as a software issue CCU-13088.


Contact Odin Technical Support to apply the resolution and prevent the issue from reoccurrence.
