The Tinderbox tends to be inflammable (what a country!). While code checkins can cause obviously cause build/test failures, a box may fail in various ways not related to checkins. Some problems fix themselves in the next cycle, others require filing a server ops bug (in mozilla.org / Server Ops: Tinderbox Maintenance).
== A unit test failed ==
If you see a unittest failure, please check the dependencies of {{bug|438871}} to see if it's already filed. If it isn't, then you should file a bug! A failing test *is always a bug*. It's either a bug in the test or in the code, but it needs to be tracked.
