A MWR2941 running 12.4(20)MR1 or 12.2(33)MRA  running high rates of Ethernet routed (IP or MPLS) traffic, usually with a routing protocol, such ash OSPF/BFD.  After some number of days, may eventually get  WP_ERR_HOST_CMD_FAILED and WP_ERR_WMM_HOST_CMD_FAILED tracebacks such as the following

Telnet session to the router will fail leaving only console access.


To hit this condition requires the MWR2941 is configured to us routing protocols, such as BFD and OSPF, and to be sending small packet sizes (mostly less than 100 bytes) at a high traffic rate (200 Mbps or more).  Larger packet sizes have not been seen to cause this failure, but may simply be much less prone to hit it.
