Thanks Morpheus.
I will add the "wait for page load" on the most critical failures and see how it behaves.
Will also migrate the script to a better VM.
SCRIPT STATISTICS MODULE
-

This module is used to get statistical performance of your scripts. For example, it can be the thread number, the number of successful executions, and the number of unsuccessful executions. A useful module when you need to call a script on certain threads, for example only 2 and 4. Then you can use the IF construct and check the thread number in the autoscript.
