sun sky error?

[RevitGary]

below are 3 error messages i get when starting a render

 

while defining light "Sun03|Light": illegal light UV sampling values

 

while defining light "Sky03|Light": illegal light UV sampling values

 

mr Sky Portal01|Light": spot light has bad spread (cos of cone angle) -0.622776

 

I didnt know a sky portal has a cone?

I figured out one set of error messages

 

while defining light "Sun03|Light": illegal light UV sampling values

while defining light "Sky03|Light": illegal light UV sampling values

 

If I turn up the shadow precision slider to default the error goes away.

 

 

The skyportal error I am still looking for answers

I had this error once, it said that and something about the sky portal being too close to a photometric light or the photometric light being too close to something else, i cant remember... . I never figure out what it was, and since i had no problems with the render, i didnt do anything, but i would also like to know the reason for this error.
