Load runner - Require Urgent answer!

[thejachaitra]

In my load runner script, I use web_url() function and I have parameterized the URL argument. When I run this script in controller for 10 or 50 Vusers, script gets executed successfully without any errors. But when I run it via controller for 10 Vusers(any number of users for that matter) for a duration of 5 Minutes (or any number of duration), Controller throws following exception 'Action.c (24): Error -27272: The "URL" argument is missing or empty   [MsgId: MERR-27272]' that points to the script line web_url() function.
Please tell me why this error is thrown? Kindly suggest me suitable solutions so that I can run my script for a fixed duration of hours.

You will be better off posting this question on Experts Exchange (http://www.experts-exchange.com/).  As I said you need to catch the exception (put a try catch around the offending call) and you might be able to get some more info out of the exception object (stack trace etc).  HTH.
