APAR status
Closed as program error.
Error description
Agents that disconnect and reconnect to a grid experience longer call or transaction times or TargetNotAvailableException after a server failover, server stop or start or other actions that cause shard movement. After all clients disconnect and a client connects again (without restarting the client JVM process) and shard movement occurs, the client does not list a CWOBJ1132I message indicating a route update was received from the catalog server. An example TargetNotAvailableException: com.ibm.websphere.objectgrid.ObjectGridRuntimeException: Unexpected error on the target partition. Resubmit the request: DefaultDomain:Grid:mapSet:1 com.ibm.websphere.objectgrid.ObjectGridRuntimeException: Too many forwards, could not find the target partition in a timely fashion.
