In the meantime maybe make a note that the backend is for testing purposes only. If the code does use flock, then it probably also needs to be set up so that files are only shared as necessary, otherwise it won't scale. Some files need to be shared (e.g. voter registration) however others can be per voter. > With regards, > Daniel.
