Thanks for the awesome project. It really really help out. I've been experiencing this issue for several months. It happens frequently (several times per day) but I didn't find a stable way to reproduce, thus I can't provide a minimal reproducer. My project runs browser tests with Kotlin 1.6.10, Gradle 7.3. It hangs frequently if I enabled recording, regardless of format (flv/mp4). Once I disable recording, no issues at all.

Environment:

macOS 11.3.1
docker desktop 4.2.0 (70708)
testcontainers 1.16.3

When it hangs, the docker ps outputs:

$ docker ps
