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.
If jobs error during this time, please re-run. Not all jobs will fail. Or you can decide to wait until the issues are resolved.
Updates will be posted in this thread as comments: https://biostar.usegalaxy.org/p/20733/#20743
Thank you for your patience, Jen, Galaxy team
