Node going stale (online/offline) all the time

We have set a stream monitoring from 3 servers using 1 parent VM.

The issue is that one node is always going stale. I’ve searched through the logs but there’s no sign of cause why this node is stale. (the only thing I’ve seen is this line on journal)

netdata.service: main process exited, code=killed, status=11/SEGV

But there’s nothing on journal or logs indicating why it is throwing Segmentation error.
