I had one recording hang last night, Server Version 1.9.5.4339 on Mini/i5/10.11 with two HDHomerun Connect. Found it was still running under the Plex Transcoder, (>ps -U user | grep plex) It disappeared from the ‘.grab’ directory as soon as server was shut down. The recording showed up on relaunch but was incomplete. (TS was only 760MB in .grab so it failed early or restarted for partial.) I will try killing the process next time to see what happens.
