I still have this problem after using all the solutions given on the forum.
And it only runs 15 browsers.
Can't go any further than that and it gets the message across.
While I have used browser hiding capability which can run 1000 browsers simultaneously.
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.
Maybe you are using "not reuse" option when
dealing with resource, and that might be problem
for deleting current line from resource - instead
it is deleting next resource line.
