Hi all,
I am using Loadrunner 12.53 patch 1 to try and record a thick application that is built on DCOM. When I launch the applicaiton from the start recording menu, I can see the number of events increasing (and if I look in the log files later, I can see the events). However when I stop the script and it tries to create the script I get an error (see attached screenshot). The error is very generic ("System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt") and I have seen lots of instances of it on this forum but not for this particular case. I am looking for some suggestions on how to fix this and get a script generated.
What I have tried so far:
1. Creating an HTTP/HTML script to see if it is just DCOM that has the issue. This script generation worked successfully.
2. Disable DEP and UAC.
3. Creating a winsocks script of this application, this worked successfully.
4. Identified the appropriate library files and added them to the recording options for DCOM.
5. Disabled C parser (this made no difference).
6. CPU and memory do not look to be overly stressed, there is a spike in CPU usage of up to 70% as it starts the script generation process
7. There are no errors or warnings recorded in the event log around the time of this issue
8. I get the same issue on two different VMs.
I am using LR 12.53 patch 1 on a virtual Windows 2012 R2 running on ESX.
If anyone can think of something I have missed or has any other suggestions please let me know.
Many thanks,
Gordon
