For both nodes I have DisableDebuggerAttachment set to 0

There is a lot to remove in those logs :-), but one thing catched my eye
whilst comparing both side-2-side (I only looked at the debian one so
far). The debian one was running nyx via python3, whereby the centos one
ran it with python2.
I did an pip3 uninstall nyx and then a pip2 install nyx on the debian
server. Then I had the output on the top right:
cpu: 88.7% tor, 54.8% nyx mem: 866 MB (21.9%) pid: 1344 uptime:
exit policy: reject *:*
So it seems to be something python2/python3 related. I'm not sure why I
used python3 to be honest.
P.S. If you want the logs, do you mind if I send them directly? Then I
don't have to remove all the other tor node details, which is quite a
lot that flies by (so this doesn't end up in the public archives -
even-though it's public info anyway).
