Hi LR R&D team,
A script can fail to be generated at the end of recording due to System.OutOfMemoryException when handling huge http body. It is caused by the fact that VuGen is a 32-bit process which is limited by OS with 2GB memory for user mode. So would you please consider providing a 64-bit version of VuGen to handle larger http body while generating a script?
One of our customers using LoadRunner Professional 2022R1 on Windows 10 21H2 encountered the limitation.
Thanks for the suggestion.
In this customer's case, they are using DFE to encode/decode the huge data. Correlation is not the main issue that caused OutOfMemoryException so even changing the correlation setting it would not be helpful in this case with the 32-bit process limitation.
Our default setting can use a lot of memory on some huge operations
and they are not suitable for every customer.
Please tell the customer to try and change the default Recording Options to :
1) General -> Code Generation -> [ ] Async Scan (unselect)
2) Correlation -> Configuration
Ignore values shorter than 
Ignore value longer than 
If he needs only Rules Scan , its better to unselect the 2 options :
 Record Scan
 Replay Scan
Then try to record again and see if helps
