Constant Crashing

[hooger]

I am running the latest version of Sonarr in a ubuntu based Docker container. Sonarr will start just fine, but when I access the webgui it starts the RSS search/refresh. It does a few shows then it crashes.

Now it doesn’t always crash in the same spot, and sometimes the error messages are vastly different. But here is one crash I was able to log

Native mono crashes [kernel fix released]

“For every action there is an equal and opposite reaction.” We’ve had quite a few reports about odd crashes, most of them known to be so called Native crashes, where mono cries out in terror and dies without telling us why. Initially this thread was to collect important information about the systems on which the crashes occurred. Since this thread was posted I’ve literally spent more than a hundred hours investigating this issue. Debugging Sonarr and mono countless times, compiled mono half …
