Description
A space-separated list of host or host groups defined in lsb.hosts on which limits are
enforced. Limits are enforced on each host or individually to each host of the host group
listed. If a group contains a subgroup, the limit also applies to each member in the
subgroup recursively.
Do not configure PER_HOST and HOSTS limits in the same Limit section.
In horizontal format, use only one PER_HOST line per Limit section.
If you specify MEM, TMP, or SWP as a percentage, you must specify PER_HOST and
list the hosts that the limit is to be enforced on. You cannot specify HOSTS.
