I have the same issue with my 871w, I know what the issue is though. I havent had much time to look to deep into it.

There is an issue with your BVI interface reconstructing packets. You also might have a couple crash logs on your flash.

*May 11 04:42:26.440: %IP_VFR-3-SYSTEM_ERROR: BVI1: IP VFR System failure - Unable to create fragment chain

*May 11 04:42:26.440: %SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=83DC0E6C, count=0, -Traceback= 0x8089554C 0x802F5DE0 0x811FA798 0x811FAD04 0x811FBEC8 0x811FD748 0x80BB56E8 0x80784234 0x80378B58 0x80399C3C 0x8039D594 0x80385E8C 0x804642F4 0x80353748 0x800827B8 0x800827B8

Keeps going on like that for a while...
