It is the latest panel dev release, which caused the unit test never to finish.

A git bisect with this command: timeout 30 pytest ../holoviews/holoviews/tests/plotting/bokeh/test_server.py shows that holoviz/panel#6459 causes it

[hoxbro]

@philippjfr, can you take a look at test_server.py? And see if there is an easy way to fix this.

[philippjfr]

😭I spent like 3 hours on this last night.

[philippjfr]

I would suggest using the serve_and_wait and serve_and_request utilities in panel.tests.util to manage the servers. It seems not going via those utilities resulted in a zombie thread.

[philippjfr]

Here's the fix in panel holoviz/panel#6492
