We've had some issues where the cache on some slave servers has stopped being updated. After some logging it seems that this is due to that if the task responsible for checking the database for updates fails the task is stopped, which leads to that the cache never gets updated.

I've posted an issue for this as well: http://issues.umbraco.org/issue/U4-11599
This is a major issue for us, so just hope someone looks into it.
