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.

Do
you have someone to review them? 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.
