If you don't encounter watchdog timeouts on 10.0-RELEASE I have no idea what's going on there. I recall a couple of users are seeing msk(4) watchdog timeouts on 10.0-RELEASE/CURRENT so I started to think about r234666 which was not merged to stable/9 and stable/8. Could you back out r234666 and let me know whether it makes any difference for you?Received on Thu Feb 06 2014 - 01:00:10 UTC
