The relevant code is: https://github.com/EVerest/everest-framework/blob/6ff5d21b512e43397c537a8167dfec2136cb654a/src/system_unix.cpp#L193

    if (pipe2(pipefd, O_CLOEXEC | O_DIRECT)) {
        throw std::runtime_error(fmt::format("Syscall pipe2() failed ({}), exiting", strerror(errno)));
    }

The issue is with O_DIRECT

For the record, the fix is to change
