Having an EADDRINUSE error happened before, here's one case:

It seems to happen on worker macstadium-macos-69e8c913 only.

Is js using random port? IIRC form our previous experiences with MacOS on TeamCity, sometimes program instances were not closed after test finished which meant that if static port was used it would be failing.

I've turned off the worker for now and will look into the exact cause of npm going missing.

@Kubuxu most tests are using random port but some things are not. Wrote some more about it here: ipfs/js-ipfsd-ctl#212 (comment)

Still an issue?

[vmx]

I haven't seen this in a long time, hence closing.
