The test that hangs is failed login with SSL.System (ssl available). Debug output when it fails:

 → StartupMessage(jimmy,world,Map(client_min_messages -> WARNING, DateStyle -> ISO, MDY, IntervalStyle -> iso_8601, client_encoding -> UTF8))
TLS: wrap result: Status = OK HandshakeStatus = NEED_UNWRAP
bytesConsumed = 0 bytesProduced = 383 sequenceNumber = 0
TLS: unwrapHandshake result: Status = OK HandshakeStatus = NEED_TASK
bytesConsumed = 66 bytesProduced = 0
TLS: unwrapHandshake result: Status = OK HandshakeStatus = NEED_TASK
bytesConsumed = 695 bytesProduced = 0
 → Terminate

Example: https://github.com/typelevel/skunk/actions/runs/4773385330/jobs/8486427544#step:13:510

When the test passes, output looks like this:

TLS: wrap result: Status = OK HandshakeStatus = NEED_UNWRAP
bytesConsumed = 0 bytesProduced = 383 sequenceNumber = 0
 → StartupMessage(jimmy,world,Map(client_min_messages -> WARNING, DateStyle -> ISO, MDY, IntervalStyle -> iso_8601, client_encoding -> UTF8))
TLS: unwrapHandshake result: Status = OK HandshakeStatus = NEED_TASK
bytesConsumed = 66 bytesProduced = 0
TLS: unwrapHandshake result: Status = OK HandshakeStatus = NEED_TASK
bytesConsumed = 695 bytesProduced = 0
TLS: wrap result: Status = CLOSED HandshakeStatus = NOT_HANDSHAKING
bytesConsumed = 0 bytesProduced = 7 sequenceNumber = 1

I'm also seeing "successful login with SSL.Trusted (ssl available)" hang as well.

OK, I think I got CI to thread-dump in 5bfe8e4.

I was able to reproduce even after bumping CE to v3.5.0-RC4 in 77ee896.

Meanwhile, after downgrading back to stable CE v3.4.x and FS2 v3.6.x in f20b6d4 I was unable to reproduce after 10 attempts in CI.

This is very similar to the issue I am observing in typelevel/fs2#3091 (comment) after upgrading, so it seems like this is a regression in CE.

Further developments:

  1. In ea55ded I mixed CE v3.5.0-RC4 with FS2 3.6.1. This one hasn't failed in 10 retries.

  2. Meanwhile, I published typelevel/fs2@df26d21 which is FS2 v3.6.1 with a commit swapping all the Semaphore(1) for Mutex. This one fails with CE v3.5.0-RC4 when I tried it in c1cc648.
