Health check status changed from true to false for Thread Deadlock Detector
Does this mean we had a system deadlock ?
I can’t really tell - it changes from true to false, so…?
Our system did go OFFLINE after this, and had to be restarted, so I suspect the answer is yes. By OFFLINE, I mean, it was still running, but it was unreachable via http.

I think I found part of the code:
