You can configure automatic job requeue so that a failed job is not rerun on the same host.
If mbatchd is restarted, this feature might not work properly, since LSF forgets which hosts have been excluded. If a job ran on a host and exited with an exclusive exit code before mbatchd was restarted, the job could be dispatched to the same host again after mbatchd is restarted.
Exclusive job requeue does not work for MultiCluster jobs or parallel jobs
A job terminated by a signal is not requeued
