what is the condition that can trigger system rebooting?

This is a kernel panic. In this specific case the message, mbuf_watchdog: 1 waiters stuck for 11 secs, suggests that something has gone wrong deep in the networking stack.

Nothing in your iOS app should be able to trigger a kernel panic; it’s always a bug in the OS itself. Can you reproduce this?

  • Hi, I am seeing this condition also on my IMAC. It started immediately after I upgraded to Monteray 12.2. Prior to that I had no problems.

    I am seeing the problem roughly every other day (I do not shutdown my machine overnight). i am sending the reports to Apple.
