Plex stops working periodically on DS916+ since update 1.20.2.3402

I’m not sure where we got off the rails here, but I just want to start by saying that I’m really trying to provide context in good faith. Yes, I’m frustrated by the lack of response, but I live and breathe full time on on your side of the fence (specifically supporting open-source software in the enterprise), so I completely understand the frustration of dealing with someone who’s not providing good repros. I also understand that I’m not entitled to support–after all, I’m sitting here on a community forum talking to unpaid volunteers (thank you for your time)–but I think in my shoes you can understand my frustration. I’ve used Plex unpaid for years, and within 1 month of buying Plex Pass, it becomes unusable for me. Not great timing…

To address your original question on downgrading: I’m mis-recalling the pain of downgrading, because I tried some other suggestions from this thread (like removing all shared users and deleting/re-adding the libraries) BEFORE I downgraded.

However, downgrading to 1.21.0.3711 fixed my problem completely. Prior to downgrading, even with the other mitigations, the problem repro’d 100% of the time: namely, that connecting from an Android client kills the server process on the Synology. If I started it and started a video within a small enough time window (usually <1 min), I could start one video, but then the process would die again when the next video queued up to start.

As for whether it’s a hang or a true process termination: I haven’t SSH’d into the box to confirm whether the process is still running, but the DSM UI indicates that it’s stopped because the Package Center UI changes from “Open” (with drop-down options to Stop or Uninstall) to “Start” (with a drop-down option to Uninstall), as if it’s not running at all. Again, clicking Start and racing the Android client into the UI works for one video, then repros again after that.

All of this happens 100% of the time on 1.21.1.3830, 1.21.1.3842, and 1.21.1.3876. It happens 0% of the time on 1.21.0.3711 (which is what I’m running now). I’ve been monitoring release notes since 3876, and I haven’t seen anything wrt Synology or crashes in the context of what I’m seeing.

Plus, this guy’s hitting what looks to be a very similar issue on 1.21.4.4079: Plex Media Server keeps stopping after new update - Plex Media Server / NAS & Devices - Plex Forum

Just want to reiterate: apologies if we got off on the wrong foot. I’m doing my best to be objective as possible here.
