Class < blank > does not exist

I am getting the below exception while running load test in PRPC system. I dont see the error when we run cases individually but only when we run it with a continous load. The below exception starts to appears in the user log file.

We see these corresponding exception in AES as well and it coming many time for all the users that are running the load test.

How can we troubleshoot this? Below is stack trace from AES

I wonder how you setup the load test. Is this error only happening when you run the load test with virtual users? I am trying to rule out the possibility of the load test script problem first.
