In a rare scenario, where a IPC error is raised at the right place, an agent that is attempting to execute an external threadsafe stored procedure/udf could hang while waiting for the FMP thread to respond, but the FMP thread is already terminated. The hang is on the particular agent, but it could be more severe in the case of federated FMP, as the agent could be holding on to some latches. | |

A workaround for this is to use db2fmpterm to kill the particular FMP, which will trigger sysc to do cleanup and wake up the hanging agent. | |
