Description Svata Dedic 2012-03-29 08:49:20 UTC

The 'scan canceled' logs do not contain enough information to pinpoint the root of excessive or long scanning. The report should contain:

* thread dump (at least 2) to hint a possible deadlock, or the time-consuming code
* proper "absorbed" chain of updater works
* classpath changes leading to the update work
* time spent in individual Indexers
* the root being indexed at the time scanning was canceled + time spent on that root

Tresholds on rate of events that trigger scanning should be added, and rate of scanning start/stop exceeds that treshold, the above information should be dumped to the log file.
