Hi I had one of my ccr's dye last night, just locked up, very annoying had just finished dinner ! /system watchdog> print watch-address: none watchdog-timer: yes no-ping-delay: 5m automatic-supout: yes auto-send-supout: no why didn't this kick in ? I'm not watching an address but I do have the timer on ? should have I expected this to have auto restarted. When I got to the box the touch wasn't working !
Hi Alex, Yes! Watchdog timer is designed to detect a software hang and reboot in that case. However, there are some cases where router /seems/ to be hung but is actually still running - examples include 100%CPU conditions, high traffic on interface attempting to connect to or BGP/routing issue preventing access. In these cases, watchdog timer will not trigger system recovery - that is why watch address helps to recover from those other conditions. Were you able to get any supout file of any use? (i.e. was there an auto-supout created?) Cheers, Mike.

Yah - if you have to power cycle, then no supout can be obtained :( If it happens again, maybe try to hook up a serial cable - usually console continues to be responsive even when other routing and packet handling processes seem to be halted. Cheers, Mike.
