During load testing, the virtual service that is built to support it is going offline by itself in between when the performance tests are running and hitting 

 

Other Details:

Capacity : 50

Think Time: Average of 300ms

TPS85TPS

Type of Virtual Service: SOAP

Note: We are not using CA DevTest NFT Test cases, instead the test cases hitting this Virtual Service are from Load Runner

Sometimes the below error is also logged

This blocks the testers from running their testing, if the virtual services goes down in between the test execution.
