Why do you think this is the same problem? It is a completely different error message, happening in a different test function. The problems reported in September were fixed in the next version of the pull request. What Peter is reporting here is probably unrelated to NetBSD, but to overloaded test hosts. QMPTestCase.pause_wait() uses a timeout of 3 seconds until it decides that the job probably has just failed to pause at all, so that the test case wouldn't hang indefinitely on failure. We can increase the timeout, but of course, that doesn't guarantee that we'll never hit it again on very slow test hosts. Kevin
