"NL-PLUGIN-ENGINE-03" error when running a virtual user validity?

I have an "NL-PLUGIN-ENGINE-03" error when I run a virtual user validity.
The first hour after the recording, the virtual user validity don't gives any error, but around one hour after the recording, I have this error.
I had created dynamic parameters but it's no sufficient, I aleady have the problem.
I give you a picture of the error.
How can I think this?
