With the rate limiting, some suspect files won't be explicitly flagged.</p> LU-4799

Isn't that right?</p> <p>The patch worked correctly in my testing, printing only one message per file.</p> <p>Merged to master aacc286fe0575d455794121264a612c29ffb7740</p> Development Rank 1|hzwi3r: Rank (Obsolete) 13204 Severity
