Update (07/22/2018, 2:30am): The scheduler is back in operation again after we cleared a large number of jobs submitted by a user. We’ll continue to monitor the system for similar problems and work with users to normalize their workflows.
The shared scheduler has been going through some difficulties, which looks like due to large number of job arrays submitted recently. We don’t know the exact cause yet, but we are aware of the problems currently working on a resolution.
Until this issue is resolved, commands like qsub and qstat will not work, and showq will return an incomplete list of jobs.
This problem only applies to job submission and monitoring , your running and queued jobs are safe otherwise.
