I suspect that parts of the script are failing intermittently. The first
thing I would do is add code to the script to verify the results of all
primary get/put operations. There is a decent article at
http://portal.opensta.org/index.php?name=3DNews&file=3Darticle&sid=3D40 that
gives an example of checking results. The bottom line is that you should
not assume all is going as it did when you recorded, and that runtime
verification is, IMHO, absolutely required.

Another possible explanation is that the server is rejecting valid
orders due to being too busy. Check application and database logs for
errors (rollbacks, server to busy errors). Also have a look at 'HTTP
Data List'=20
under test results to check for 4XX and 5XX response codes to narrow
down where the problem is.
