When RACF® detects that a task in the RACF subsystem address space has stopped, it tries to restart the task. RACF makes a number of attempts to restart the task, and if it is unsuccessful, gives up and issues error message IRRB041I. The error message identifies the module name that it cannot restart. When this happens, use the RESTART command to try to restart the task associated with the module. See Restarting a function in the RACF subsystem for more information. If you cannot restart the task, use local procedures to determine what the problem is and correct it, and then restart the task.

It is possible that a task stops and RACF does not detect the problem, because it is busy doing something else. In this case, it will appear as if something that should be happening is not. For example, you might enter RACLINK commands but nothing happens. Or output from directed commands that you know executed might not be returning to the RRSFLIST data sets. If this is the case, use the RESTART command to restart the task associated with the actions that are not happening. For example, if nothing happens when you enter RACLINK commands, try restarting the RACLINK task. If output is not returning to the RRSFLIST data sets, try restarting the OUTPUT task.
