I’m quite certain this is not a hardware issue. I already had the same problem with my previous case, which had a different cooler, different motherboard, and different power supply. The only component that hasn’t changed is the CPU — and I previously used this CPU in my main PC without any issues. Also, the CPU cores are heavily limited, and during the Plex maintenance tasks, Unraid runs at only around 60% total CPU usage. In addition, I have other very CPU- and IO-intensive processes running on the system as well, and none of them cause any issues — the system is completely stable under those loads. If I had to guess, I’d suspect that something related to the iGPU and FFMPEG might be causing this — but I don’t have enough knowledge in that area to say for sure. Has anyone seen similar behavior or knows what I could check next? Are there any good logs or debug options I could enable to get more insight into what’s going on?

Unfortunately, this issue has been present for me for a few months now. I have already tried binhex-plex, binhex-plexpass, the Linuxserver Plex version, and finally the official one. Each time, a new container and new appdata were created accordingly. I have tested it with and without QuickSync — always the same behavior. The problem has persisted across several Unraid versions.

Hi everyone, I am currently struggling with a recurring and very frustrating issue on my Unraid server and would really appreciate any advice. I am running Plex in a Docker container using plexinc/pms-docker, with Intel iGPU (Quick Sync) enabled for hardware transcoding. Almost every day, during Plex scheduled maintenance tasks, the server suddenly reboots — it looks like an instant hardware reset, as if the reset button had been pressed. This typically happens after 30–40 minutes of Plex running its maintenance tasks. In earlier cases I also experienced full system freezes, but lately it has mostly turned into instant reboots. Unfortunately, the syslog always stops about 10–15 minutes before the reboot, so no kernel panic or other obvious error is logged. What I have already tried: Limited the Plex Docker container to 8 CPU threads and 8 GB RAM Performed Live Memory Tests (no errors found) Checked syslog (no OOM killer, no kernel panic, no obvious issues) Monitored drive temperatures and health (no issues found) Running Unraid 7.1.3 Using the official plexinc/pms-docker container This behavior seems highly correlated with heavy I/O and GPU load caused by Plex maintenance. I would appreciate any suggestions regarding: Further debugging steps (kernel log settings, hardware tests, extra logging on USB, etc.) Known issues or limitations when using iGPU (Intel Quick Sync) with plexinc/pms-docker on Unraid Links to similar forum threads or external guides I will attach my latest diagnostics ZIP to this post. Any help or guidance would be greatly appreciated. unraid-diagnostics-20250613-1401.zip

worked like a charm, Thanks!

Hi everyone, I'm having trouble formatting an NVMe SSD in Unraid. I recently installed a Samsung 980 Pro 500GB SSD into my server, which previously had Ubuntu installed on it. I added it to a new pool in Unraid, but it shows up as Unmountable disk present with the following details: When I proceed with formatting, Unraid appears to start the process but then immediately reverts back to the same state, showing the Format option again. The drive remains unmountable. Since the SSD is in a location that is difficult to physically access, I would prefer to resolve this through Unraid directly rather than removing and wiping it externally. Has anyone encountered this issue before? Any suggestions on how to force the format or clear any remnants from the previous Ubuntu installation? Thanks in advance! unraid-diagnostics-20250212-1201.zip
