Hello. I recently launched a Galaxy CloudMan 18.05 instance on an AWS m5a.4xlarge server. Some Galaxy jobs are not dispatching (i.e., they stay gray in the history and never turn yellow). If you resubmit the same job, it will frequently immediately dispatch, but the original hung job never starts running. The stuck jobs seem to occur randomly. Please let me know if anyone has any advice regarding this (e.g., a configuration recommendation that will avoid the problem or a technique to un-hang an enqueued job). Thank you.
