LSB_MAX_JOB_DISPATCH_PER_SESSION=integer
This is the maximum number of job decisions that mbschd can make during one job scheduling session. The system sets it automatically during mbatchd startup, but you can adjust it manually:
LSB_MAX_JOB_DISPATCH_PER_SESSION = Min (MAX(300, Total CPUs), 3000)
Both mbatchd and sbatchd must be restarted when you manually change the value of this parameter.
Min(Max(300, Total CPUs), 3000)
MAX_SBD_CONNS in lsb.params and LSF_NON_PRIVILEGED_PORTS in lsf.conf
