Random crashes on DS216+II, DSM 6.2.3, PMS 1.22.3.4392 and earlier

Synology DS216+II
DSM 6.2.3-25426 Update 3
I had crashes on 1.21.1.3876, updated to 1.22.3.4392, and had another crash, so I decided to post the logs.

Crashes happen once in a few days, sometimes at night, sometimes during the day. I created Tautulli “Plex Down” notification to know when it happens.

I do not have on/off schedule on my DSM.
Plex Scheduled Tasks are set to 3pm and 6pm.

Tautulli notified me about Plex stop at 3:20 AM (on 1.22.3). No one used Plex at the time, so it must be a result from some background job. Also there’s nothing in the history of Sonarr/Radar during that time, so no new content was added.

Before the crash I had “Enable Plex Media Server debug logging” checked, and verbose set to off.

Manual archive of the folder before the Plex start: Logs 240421.zip (9.6 MB)

Downloaded after the Plex start from UI: Plex Media Server Logs_2021-04-24_15-15-43.zip (5.4 MB)

Just in case, now I disabled “Send crash reports to Plex” so I’d have a DMP file instead in the future. For now I’m waiting for another crash to post it.
