On Ubuntu Focal running the same test some times in a row

$ BITCOIND=/home/hebasto/bitcoin/src/qt/bitcoin-qt QT_QPA_PLATFORM=minimal ./test/functional/feature_versionbits_warning.py

I eventually got

AssertionError: [node 0] Node returned non-zero exit code (-11) when stopping
...
ConnectionRefusedError: [Errno 111] Connection refused
[node 0] Cleaning up leftover process

I have just tried to reproduce this on 21.04 but have been unable to do so. QT_QPA_PLATFORM=minimal did not work on my system (plugin could not load application fonts) so I tested with QT_QPA_PLATFORM=offscreen, running the test 20 times:
```
will@ubuntu in bitcoin (032ceb1 🏷  v24.0rc2) [?] via 🐍 v3.6.12
❯ for i in (seq 1 20)
      BITCOIND=/home/will/src/bitcoin/src/qt/bitcoin-qt QT_QPA_PLATFORM=offscreen ./test/functional/feature_versionbits_warning.py
  end
```
It seems unlikely that this is related to the QPA platform, but do you think it's worth testing on a 20.04 VM too?

Agree.

It won't hurt :)

Can this be closed, given that the bug is fixed in recent version of Ubuntu?

I think so. Is this even a bug in Bitcoin Core?
