6. If you have filed a service request with Mercury, what have they told you at this point with respect to your issue?
Not yet

Dear All,
I request your views for the below,

I
have prepared, enhanced and debug the LR scripts according to the test
scenario. Script has no issues. Script is running well for 30 users
with no errors/warnings.
For 40 users LRController is generating
logs with "HTTP 500 Internal Server Error". My perception with the
situation is that the Server is not able to handle the HTTP requests
generated by 40 Users; where as it is able to handle the requests for
30 users.
Can anybody throw some light, is my understanding correct.
Please let me know for further information.

Scripting and/or script parameter and/or runtime settings can cause the script to make unusual requests that result in http-5xx errors. . .

Your perception may be correct (key word = may). If this situation is repeatable, I suggest you get monitoring in place and perhaps some key people to monitor systems during the test. The root cause possibilities at the level of detail you provided, are vast in number.
