So we use Galaxy to teach our bioinformatics courses and we have an install of Galaxy in the Amazon cloud that we have customized with various tools.  However, we don't touch the Galaxy code base itself.  Recently, we've been getting errors in creating and running workflows.  We are getting "locked database" errors, sometimes the steps seem to run out of order, and sometimes the entire workflow just hangs.  Also, the workflow editor seems to be having issues, like it allows connections between outputs and inputs of entirely different datatypes.  Has anyone seen any issues like this?
