I suppose it hangs on a read() because the other side didn't have
anything to say... Just a guess, feel free to flame :)
I checked the logs, here are some lines from this morning. Not sure
around what time it crashed, but I suppose it started to not respond
when we wouldn't see the PING anymore.
Alex, do you think wifidog would still work even if the ping_thread is
hung on a read()? The fw_counter() is still happening...
