Description Aakash Jain 2020-09-11 11:26:26 PDT 
EWS should mark build as failed when layout-test log lines are exceptionally high. Exceptionally high log lines are usually indicative of a problem (e.g.: too much logging turned on by mistake). It can put a very high load on infrastructure and significantly slow it down.

For e.g. https://ews-build.webkit.org/#/builders/32/builds/17165 had over 9 million log lines in layout-test run (usually there are about 70k log lines). This was because, the patch being tested accidentally turned on some logging. This extra logging significantly slowed down the infrastructure (buildbot) and was later reverted in r266884.
