Hi Jacek, It's a bug, sigh. You can get around it by using the following directive: cms.space mwfiles linger 0 Notice the addition of another option. The code wants at least one option and while it accepts and uses mwfiles it doesn't recognize that it valid as the only option. The error message in the log file sort of tells you that.

The log file attached. Are you at slac? Maybe you wanna stop by?
