To give you further insides of it why it happens there are several reasons:
- The
debugserver
crashed or was terminated by another process - More likely the
debugserver
had a memory or CPU usage peak which invoked termination.
To fix this, update your version and see for updates or wait for next patches, releases from apple.
Also check for specific processes that use up a lot memory or CPU usage below (e.g. Chrome / Firefox) terminate them and observe it happen more frequent or not at all anymore.
I think that’s all what you can do on YOUR side. I hope that brings a bit more clarity where the problem lies.
