Server Version#: 1.43.4.10903
Platform: Docker (LinuxServer.io), Unraid, x86_64
Server UUID: 0d1867bdb6d94e44f0ec315bb345d86c86069556
I have been experiencing ongoing crashes with my unraid server. This morning the unraid server completely locked up again at 09:25. The Plex log files indicate (confirmed via minidump upload in Plex Crash Uploader.log, not a manual stop/restart) crashes 6 times over the last ~9 days: Sep 9, Sep 12 (x2), Sep 14 (x2), and Sep 18.
Most recent crash: Sep 18, 2026, 09:25:06 (GMT-4). Server was down until 09:49:25 (when I managed to complete a reboot), then Crash Uploader processed a minidump at 09:49:27, confirming an actual crash rather than a clean stop.
The last lines in the log before it died:

That 401 response is the last line in the log. The request came from a WAN IP with an empty/blank token (Signed-in Token ()), which triggered a MyPlex auth token refresh (53 access tokens) followed by guest authentication and a 401 rejection, immediately after which the process appears to have died.
I noticed the 1.43.4.10903 changelog lists PM-5590 (“In rare instances, a timeline request can crash the server”) as fixed in this build, along with PM-5592 and PM-5964 (other HTTP/POST crash fixes). Given my crash pattern lines up closely with a timeline-request-related crash despite running the build that’s supposed to include that fix, I wanted to ask:
- Is this likely a different/unfixed timeline crash, or could the PM-5590 fix have missed an edge case (e.g. involving guest/unauthenticated WAN requests specifically)?
- Could someone on the Plex team pull the minidump for my Server UUID at the Sep 18 09:25 crash timestamp (and/or the earlier Sep 9/12/14 crashes) and let me know what function it’s actually crashing in?
Full log bundle is attached. I am not sure if Plex is causing the entire Unraid server lock-ups. I had the server running with all plug-ins and dockers disabled except Plex and still experienced crashes. Thank you for your help!
