 This Non Job User Process Reaper for LSF will remove any unauthroized users from the
 compute hosts once their jobs have left those system.  It provides an optional grace period called the LSF_LINGER_TIME that you can set in the lsf.reaper file in your $LSF_ENVDIR.  The value is in seconds.
 
-You can optionally set a LSF_SLEEP_TIME to a value in seconds as well.  As you clusters become larger, you may not want them querying the batch system as much, so increasing this value may be practical in such cases.  This value is also in seconds.

 You can also optionally set LSF_EXCLUDED_HOSTS to a space delimited list of hostnames that should be excluded from the reaper check.  An example of a host such as this would be a Login Node that is running LSF daemons for some reason.  As always, LSF Administrators are not reaped, so this would not have to include hosts in the LSF_MASTER_LIST.
 
+Additionally, there are two parameters that allow you to exclude LSF users from LSF user groups that should be allowed to login to the host even if there are not jobs running, for example a hardware maintenance group that though they do not manage LSF, they need to login from time to time to check the status of the system.
+
+Those settings are LSF_EXCLUDED_UGROUPS wich needs to be set to a space delimited list of LSF user groups.  Non LSF user groups will be ignored.  The second parameter is the LSF_UGROUP_REFRESH, which instructs the elim.reaper how often it should recache the list off LSF users in those user groups.  The default is 3600 seconds or once an hour.
