Database Profiler outputs incorrect value of property "keysDeleted" for a remove operation when a write conflict occurs. Other write operations and some other properties (like "keysInserted") are probably affected in the same way. Instead of setting "keysDeleted" value to the actual number of index keys deleted, the system accumulates the number of index keys deleted over all operation execution attempts, including retries, that happen in response to write conflicts.

Here is one place where the property "keysDeleted" value is accumulated.
