How conflicting limits are resolved
Similar conflicting
limits
For similar limits configured in lsb.resources, lsb.users, lsb.hosts, or
lsb.queues, the most restrictive limit is used. For example, a slot limit of 3 for all users
is configured in
lsb.resources:
Begin Limit
NAME = user_limit1
USERS = all
SLOTS = 3
End Limit
This is similar, but not equivalent to an existing MAX_JOBS limit of 2 is configured in
lsb.users.

819 user1 PEND normal hostA sleep 1000 Jan 22 16:34
Two jobs (818 and 819) remain pending because the more restrictive limit of 2 from
lsb.users is enforced:
% bjobs -p
JOBID USER STAT QUEUE FROM_HOST JOB_NAME SUBMIT_TIME
818 user1 PEND normal hostA sleep 1000 Jan 22 16:34
The user has reached his/her job slot limit;
819 user1 PEND normal hostA sleep 1000 Jan 22 16:34
The user has reached his/her job slot limit;
If the MAX_JOBS limit in lsb.users is 4:
% busers

and user1 submits 4 jobs:
