I get this error occasionally: "/bin/sh: 1: /opt/galaxy/web/database/job_working_directory/000/100/galaxy_100.sh: Text file busy" When this occurs, the step fails outright. Resubmitting the step resolves the issue and things run no problem. If this error appears early in a long workflow, I have to manually resubmit ALL dependent steps... what a pain! Perhaps this is something the Galaxy job scheduler can look out for, flush() the system, sleep() a second or two to let the file write and close, and then rerun. A more fault-tolerant way of running workflows without unnecessary human intervention.
