There are three specific issues that I am facing while executing from the Controller -
1. Error: Exception was raised when calling event-notify Vuser function in extension parameng.dll: System Exceptions: EXCEPTION_ACCESS_VIOLATION
2. Error: Exception was raised when calling per-thread-init function in extension parameng.dll: System Exceptions: EXCEPTION_ACCESS_VIOLATION
3. The complete parameter value from the file is not retrieved.
Instead of retrieving - /<severpath>?&x=abc&y=def&z=mn o, it is just retrieving a part of the parameters. In such cases, the URL looks like the following -
When you load your virtual user all of your data file goes into RAM. So with a 287MB data file it would take fewer than 16 users to exceed the entire 4GB address space of your 32 bit based load generator.
Likely you are simply exceeding the design limits of the program. It is not generally recommended that you use a phone book for your parameter file. If you feel that you must cover every possible combination and edge condition then you are likely combining functional and performance testing into one effort.
