Sonarr stops, can be restarted but soon stops again

I have sonarr running on linux mint v2.0.0.3004 with mono 3.10.0. It was running fine until a couple of weeks ago and now suddenly it just stops running several times a day. I can restart it with terminal command but it soon stops again. I have enabled trace logging and i cannot see a reason for the issue. I do have 9 indexers enabled which were not an issue initially. I have disabled down to just one indexer but it still stops. Other forum listings mention reload and dropping the config entirely but that hopefully is not required. I have the trace logging if anyone can tell me the best way to provide them to be reviewed.

Possibly this issue? Native mono crashes [kernel fix released]
