Maximum Number of Semaphore Undo Structures Allowed System-wide

Rose allocates a semaphore undo structure for each executing application. If a rehosted application fails to run concurrently with other instances of the application (or alongside any other rehosted application), it may be because this limit has been reached.

The number of semaphore undo structures permitted on the system should be greater than or equal to the maximum number of concurrent Rose processes that will ever run simultaneously. If you do not have any idea, start with 100.
