[En-Nut-Discussion] Need help: interrupt resets device.

[Dmitry Beklemishev]

Harald, thank you for your reply. I tried to completely disable watchdog and
all threads, but it does not help. By the way, behavior of the program can
vary -- sometimes it can just lost the network instead of restarting,
sometimes the interrupt begins to occur very frequently without any external
event that causes it... I tried not to use Nut/OS interrupts API (using
SIGNAL(SIG_INTERRUPT3)), but the result was almost the same.
Thank you for support,
Dmitry.

Dmitry,

I don't think that the interrupt is the problem. Disable your watchdog 
in order to see, if that causes the reset. If you created additional 
threads, increase their stack space.
