We are trying to evaluate astra load-test and when i try to re-rerun the scripts in debug mode ,it works fine, but when i try to run them in Controller/Load mode, then i get the following error in few pages which is stopping me from proceeding.

My webpages have loads of javascripts in them and used DHTML layers too..

Error -10399 : An exception was raised while calling invocation function in interpreter extension ActScrExt.dll: System Exceptions 0xc0000005: EXCEPTION_ACCESS_VIOLATION. [MsgId: MERR-10399]
Notify Transaction User_logged_ELPLNM01_3 ended with Abort status (Duration: 1.0313). [MsgId: MMSG-16998]
Ending Vuser... [MsgId: MMSG-15966]
Vuser Terminated. [MsgId: MMSG-15963]

Is it a problem with my software or scripts or with tool itself?
