            Bug ID: 216413
           Summary: EWS should mark build as failed when layout-test log
                    lines are exceptionally high
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aakash_jain at apple.com

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.
