30s is the default value of the streaming replay conflict timeout. After that the startup process cancelled the session running pg_dump. So it's not an intentional timeout in the test.

It's not surprising that pg_dump takes 30s on that old a machine. But more than 2min still surprised me. Is that really do be expected?
