I see one larger job queued since Sun 29 Jul 2018 01:15:09 PM (UTC). This was about three hours ago and is a normal amount of time to have a job queue (can take up to 24 hrs, depending on a few factors).
If the job stays queued longer than 24 hrs, first double check your inputs (appear to be Ok, but I didn't review all upstream jobs) and let us know. There are no known cluster issues that would impact this run at this time.
Thanks! Jen, Galaxy team
