There are unexpected ongoing issues at Galaxy Main involving job processing. We hope to have this resolved within the next few days, if not sooner.
The jobs are queued. Allow them to process. Stopping and restarting will not make this go quicker. If any fail, re-run. Not all jobs will fail.
Updates will be posted in this thread as comments: https://biostar.usegalaxy.org/p/20733/#20743
Thanks, Jen, Galaxy team
