[En-Nut-Discussion] anyone had probs with setting SO_RCVTIMEO causing lockups?

[Damian Slee]

Turned out to be a really wierd problem with a call to memcpy_P() in my code.  
Despite using it else where in the same thread, this instance caused strange problems.

Replaced it with two _LPM() calls, and I am not having the problem now?

Using GCC 3.3.

Damian,

We are using socket timeouts in most of our own applications.

Because of a bug in timer handling, make sure to keep the timeout
above 62 millisecs. This is also true for NutSleep().

90% of lockups are caused by loops without NutThreadYield().

(Just in case: If you are calling input or NutSleep() functions
in your loop, NutTreadYield() is not required.)

Harald
