LSB_SYNC_HOST_STAT_LIM=Y|y|N|n
Improves the speed with which mbatchd obtains host status, and therefore the speed with which LSF reschedules rerunnable jobs: the sooner LSF knows that a host has become unavailable, the sooner LSF reschedules any rerunnable jobs executing on that host. Useful for a large cluster.
This parameter is enabled by default. It allows mbatchd to periodically obtain the host status from the master LIM and verifies the status by polling each sbatchd at an interval. It is recommended not to disable this parameter because it may then take longer to get status updates.
