MaxRepairCollection

To keep track of various cache metrics, the system stores some caching information for automatic analysis to determine if corrective measures need to be taken. The default limitation for this storage is 5 megabytes. This data is not used for historical reporting or analysis, and it is used only by the system while a server process is running. Once the limit is reached, the system purges all cache tracking information.

The log file message is similar to:

Cache Repair: maxed out memory at 5MB, purging cache repair data
