BRX Hardware Watchdog Timeout

[JeffS]

Duplicated my answer here since it was pertinent to this thread as well.

So turns out I had a bug in the program for the last 2 years that caused the SETUPIP to execute once a minute.  It appears that after enough of these it causes the OS to crash, my guess based on your comments is that occasionally I am unlucky and the crash happens during the flash writing operation and the PW config is lost.  At least that is my assumption.   

I tested this by having the instruction fire once per second and I very consistently crash the OS after 1408 seconds.  Each time it did this I also lost the password configuration.  Figured this might be useful for you to see what exactly is happening to cause the OS to crash after writing the IP stuff 1408 times.   Related thread: https://forum.hosteng.com/index.php?topic=3852.0

What is interesting is that it doesn't affect the H2 Do-more this same way as those are operating in the field without a hitch even saddled with this bug.  That or they are on older firmware(many on 2.7.5) that may not be affected for some reason.
