LSB_MBD_MAX_SIG_COUNT=integer
When a host enters an unknown state, the mbatchd attempts to retry any pending jobs. This parameter specifies the maximum number of pending signals that the mbatchd deals with concurrently in order not to overload it. A high value for LSB_MBD_MAX_SIG_COUNT can negatively impact the performance of your cluster.
Integers between 5-100, inclusive.
