This is at http://usegalaxy.org (Main)?
The job queue is busy but two days seems like a long time. Did you by chance stop and restart the jobs? Or did you have other jobs queued (in other histories will count as well) before these? Jobs run in the order submitted, in turn with other users on the instance.
If you continue to have problems, please send a shared history link with your galaxy user email to email@example.com and we can look into this further.
Thanks! Jen, Galaxy team
