APAR status
Closed as program error.
Error description
Containers send one-way ORB requests to the catalog server to become eligible for placement. Since this is not two-way communication, it is possible for the request to be lost without generating any failures. Thus, the containers seem to start (CWOBJ1001I message can be seen) but, placement of shards on those containers (CWOBJ1511I message) does not occur. The container shows no failures and continues to run. However, the container server will not be an active part of the grid. Also, the container will not be displayed in the showPlacement output and the number of containers counted in the showPlacement "Total known containers" output will be less than the number of containers that actually started.
Local fix
