The ntrtscan.exe process and the Windows 8 Metro Communication Apps database engine enter a deadlock when Windows 8 Metro Communication Apps tries to perform a database maintenance operation on the database (DB) store.
The following event appears several times in the event viewer:
taskhostex (2200) The database cache size maintenance task has taken 60 seconds without completing.
This may result in severe performance degradation.
Current cache size is 83 buffers above the configured cache limit (396 percent of target).
Cache size maintenance evicted 0 buffers, made 52515 flush attempts, and successfully flushed 0 buffers.
It has run 291324 times since maintenance was triggered.
