Our datasync server ran out of space recently. Cleared up some logs to get it back running for now, but before adding more disk to the server, I noticed that the /var/lib/datasync/mobility/attachments/.trashbin folder is filled with lots of old files that don't seem to be getting cleared out. Is it ok to go in and delete these files manually ? Seems others have this problem also, but did not see if it is ok to delete manually. Thanks
