@svyatonik can you look into it?

[svyatonik]

Hmm...Sure

[debris]

Thanks! 😉

@debris ~2 hours - still running smoothly on my laptop :/ I'd suggest adding #[ignore] for these tests if this is an urgent task - to fix this properly, I need to rewrite all tests that are using TCP/IP stack for in-test communication (i.e. almost all tests in cluster.rs). This will take some time (probably post-retreat time).
