Re: executing 2 nGrinder Agent on the same machine

Sorry for late response. I was so busy to release the other product so far.

The message you've got is to indicate that there are some failure while sending the periodic message to controller and it's ignoble if it's not occurred too much. The controller is tolerable enough to eat the trivial errors.

It's usually occurred when you made too much traffic which the underlying OS can not handle well. If you use linux instead of the Windows you currently use, you may see fewer error messages.
