Or low mbuf situatio= ns? (netstat -s after a bit of uptime may show increasing IP output error counters). Background: As the full packet trace (without timing) by itself is not sufficient to reproduce the issue, one possibility is that very infrequent error handling is involved in the introduction of the problematic state - a= nd this may only happen on quite busy machines where mbuf allocation, or packet output issues are showing up. --=20 You are receiving this mail because: You are the assignee for the bug.
