I can add an option to the OnStartupTriggeringPolicy to only roll if the file meets or exceeds a minimum value. The default would be 1 byte.
Also, I believe I introduced another bug. The file is now going to roll every time a reconfiguration takes place, which is obviously incorrect. I need to fix that asap. The PatternLayout does not support interpolation of the header and footer but the Configuration does. All attributes are interpolated as the configuration is read. You could create your own custom Lookup to get the processId, but that may be something we should add to the standard set of properties. Actually, the triggering policy could write to the file since it has access to the Manager.
