On Solaris 11 OpenIndiana (from 2022), aside from the 4 well-known test failures in 'features/archives', in 64-bit mode I also see a test failure in category 'features/output-sync', with an error message "timeout after 10 seconds".
I don't know why only this 1 out of 3 output-sync tests (compared with OmniOS) and why only in 64-bit mode. Find attached the logs.
