It is difficult to understand about what the problem is ... so you can try to find it by yourself for example using this wiki thread:
For example - about the limitations:
And finally -
As Providers (agents)
And read this small thread:
I hope that now you can see what seems to be an issue.Also I am not using any kind of virtual machines for this.As you can see i have 8 physical cores and in the Metatester agents manager it shows that i have 8 agents active, connected and running.But on the website it shows only 3.It did show 8 but suddenly 5 of them disappeared.Same thing happened in my first few days when I installed the manager, but then all of my agents disappeared from the website.They started working only when i have reinstalled them one by one.Have I made a better explanation now?
Thank you :)I feel stupid now that I did not even notice that.But at least that concern was resolved now.
