Further to the mail below, 1. Test bug-1559004-EMLINK-handling.t possibly just needs a larger script timeout in mux based testing. I can see no errors in the 2-3 times that it has failed, other than taking over 1000 seconds. Further investigation on normal non-mux regression also shows that this test takes 850-950 seconds to complete at times, I assume increasing the timeout will fix the failures due to this. 2. We still need answers for the following - add-brick-and-validate-replicated-volume-options.t Details on where it is failing is given in the mail below (point (2), points to possible glusterd issue again). This does not seem to correlate to the other glusterd stale port map information (as glusterd is restarted in this case), so we possibly need to narrow this down further. Help appreciated!
