    initial v1  
    1 The first screen grab I uploaded shows the status in top when the router crashes during a BitTorrent download.  "sirq" will increase or decrease depending on the throughput of the download in near realtime.  When the server slows down, it's "sys" that spikes (sometimes over 90%). Several processes (ie, hostapd, resetbutton, watchdog etc...) will consume a high percentage of CPU cycles when the router either bogs down or crashes.

Several processes (ie, hostapd, resetbutton, watchdog etc...) will consume a high percentage of CPU cycles when the router either bogs down or crashes.  Router memory consumption increases and the free memory reported in top can be quite log (ie, less than 5MB).  While doing a continuous ping of the LAN address of the router I also see waves of high latency (ie over 1000ms) and dropped packets when the router is in this busy state.

    3 The second screen grab shows the direct download of a large .iso file.  "sirq" stays in the 22-25% range while maxing out my 50Mb connection.  Load average stays very low (the 5 and 15 minutes load averages are higher because the router had just been rebooted after the BitTorrent download crash).
