Server Version#: 1.41.5.9522 Player Version#: 10.26.0.2578 Hi, I’m using the android app to play videos and if I choose “automatic conversion” then I always have an error message saying an error occured. When looking into the logs I get a warning “Transcode runner appears to have died” and some verbose logs about “destroying existing session”, “deleting stale file” and “killing job” (not sure if related). If I select manually another quality (like 720p), the transcoding and the streaming starts with no issue. Please find attached the debug logs from the server (the most recent logs should show the last attempt). Thanks for your help.

Hi @ChuckPa my bad I though I had enabled it. Here the logs after restart and redone the error. Thanks ! [Plex Media Server Logs\_2025-03-12\_19-33-39.zip](https://forums.plex.tv/uploads/short-url/hi3j5AUpY3UmzZ0X8cZ8s7j4kZG.zip) (1.6 MB) ---

the /transcode path is a volume (the PMS is a docker container on a Unraid server) mapped to /mnt/user/transcode on the host: ![image](https://global.discourse-cdn.com/plex/original/4X/8/a/7/8a7c8ac7219ee2a12e7d03426cb5145218b89bb0.png) It’s a folder on a local SSD on the NAS. ![image](https://global.discourse-cdn.com/plex/original/4X/1/5/5/1558f1374eba5725e0b0e74e115cb34e03c1d8d5.png) Right now the 3 subfolders (Detection, Downloads and Sessions) are empty, but if I start a streaming from Plex Windows by manually converting the video (triggering the transcoding) I have a new folder in Sessions: ![image](https://global.discourse-cdn.com/plex/original/4X/4/a/e/4aee267b66dc9d5bf9591c3183c0f350a08c37b8.png) ---

thanks. Now it’s making sense. Please do the following: 1. As root: `sysctl -a | grep fs.inotify.max_user_watches` – this will tell us how many watch table slots exist 2. For all your library sections, Count every folder – something like: (3 media top level directories shown here) ```auto find /media1 /media2 /media3 -type d -print | wc -l ``` If you have more media dirs than max slots -AND- you have auto detect enabled -THEN- we have found it. ---

Ok so I removed the docker volume /transcode, restarted the server and now it seems to work like a charm. I’ll keep testing a couple of days to be sure. Don’t know if it’s better or not to have a volume for the transcoding. ---

Now to investigate why where `/transcode` maps to doesn’t work. Is it Linux filesystem or NTFS ? I can confirm ext4, xfs, and btrfs work as expected ---

Well the previous volume and the current docker are stored on the same SSD (btrfs). But I spoke too quick: I still have the issue but it seems not for all medias. I tried many series which keeps showing me the error message on automatic conversion (the manual conversion is still working I tried many resolutions from 720p to 480p without any problem). On the other hands, I tried many movies with no issue at all. When the automatic conversion succeeded it’s always for 1080p and bitrate between 17 and 22 Mbps. When it fails I don’t know the target quality, I have the error message before. So far, I found just 2 movies I cannot watch, and it doesn’t seem to be random : I kept trying the automatic conversion for about 5 times and I always got the error message. Done the same test for a working movie : always good. So could it be related to specific files? I tried movies from different media (I have 3 hard drives, same model the 3 of them) and I could find medias in all drives which are failing or succeeding. Just in case, I reactivated the debug logs and made 2 tests : first movie Gravity (OK) and then The Tuche 4 (ERROR) : [Plex Media Server Logs\_2025-03-14\_07-22-13.zip](https://forums.plex.tv/uploads/short-url/6mlXhJ8FvmQexaVaf6tSquZgB1s.zip) (1.8 MB) Oh FYI the docker image I’m using is : [https://hub.docker.com/r/linuxserver/plex](https://hub.docker.com/r/linuxserver/plex) And the docker command (I recreated the transcode volume since it’s recommended by linuxserver, and because I found “permission denied” errors in the logs without it): ```auto docker run -d --name='plex' --net='host' --pids-limit 2048 -e TZ="Europe/Paris" -e HOST_OS="Unraid" -e HOST_HOSTNAME="SylTower" -e HOST_CONTAINERNAME="plex" -e 'VERSION'='docker' -e 'PLEX_CLAIM'='claim-***' -e 'PUID'='99' -e 'PGID'='100' -e 'UMASK'='022' -l net.unraid.docker.managed=dockerman -l net.unraid.docker.webui='http://[IP]:[PORT:32400]/web/index.html' -l net.unraid.docker.icon='https://raw.githubusercontent.com/linuxserver/docker-templates/master/linuxserver.io/img/plex-logo.png' -v '/mnt/user/media/':'/media':'rw' -v '/mnt/user/transcode':'/transcode':'rw' -v '/mnt/user/appdata/plex':'/config':'rw' --device='/dev/dri/' 'lscr.io/linuxserver/plex' ``` ---

@kerbys This is a local host issue. When using docker, we can’t see what’s happening with the host filesystem. The best I can give you are the Linux Tips. (for fs.inotify.max\_user\_watches) > [@Linux Tips](https://forums.plex.tv/t/linux-tips/276247/9): > > Increase the number of directories Linux can monitor (inotify) for PMS The default size of the Linux inotify table is 8192 directories (\*1). When PMS is configured to update automatically when media is added, with properly organized media, especially music, this table rapidly fills and exceeds the default allocation requiring you to increase it. The solution to this is straight forward. Increasing the table size is easy. The first step is to determine how many directories to alloca… I will share that my experience with BTRFS has not been favorable. I’ve watched many Synology users lose their entire storage volume (media and PMS) due to BTRFS. IMHO, it has not proven itself to be stable My personal choice is the one proven by enterprise servers – xfs. It’s more robust and a heck of a lot faster. It also scales VERY well. FWIW: 12x 12TB HDDs, RAID 6, xfs format, pulls 2.0-2.1 GB/sec ---

Isnt this automatically run out at plex can often take up 100 thousand folders? Im running on unraid and had zero problems up till march time. This happens on two unraid hosts that were both upgraded to v7. Jellyfin works fine but plex doesnt. Theres numerous issiues reported on the forums about transcoding problems and its being ignoured and marked as a “not us”. Im happy to work with anyone to resolve as its kinda frustrating as there is defo something up. ---
