Event ID 4999 is logged on an Exchange Server 2010 Client Access server

Today I just found an error message in my exchange server with the Event id 4999



This issue occurs because the special characters in the database name cause an IndexOutOfRangeException exception.

This exception crashes the MSExchangeServicesAppPool application pool

Resolution :

Just we need to apply the Roll update 1 for Exchange 2010 SP2
