Question

I am instantiating and sending multiple instances of HTTPService
On a Mac, however, many of the calls fail with a 2032 error.

It works as expected on PC (I get all 100 results as successful) but on a Mac, I get wuite a few that fail.
Why is this happening and how do I get around it?

Answer 1

It seems Win7 and Mac OS X block very quick requests to different addressed.
Adding a 1 second timeout works fine
