I don't get trap after 2 hour, but already see next trouble:

===
PING 10.200.0.1 (10.200.0.1): 56 data bytes

--- 10.200.0.1 ping statistics ---
100 packets transmitted, 97 packets received, 3.0% packet loss
round-trip min/avg/max/stddev = 0.188/0.268/0.356/0.044 ms
===

w/o patch, but witch fresh source I see same trouble: after 12 hour 7% lost.
netstat -i don't show any errors.
