Symptoms
In Microsoft Windows Server 2003 with Service Pack 1 (SP1), a program that uses structured exception handling may stop responding for several seconds. Programs that use structured exception handling include Microsoft SQL Server.
Resolution
This problem occurs because Windows Server 2003 SP1 includes a change to the memory manager. This change may make the validation process of exception handling routines take a long time if the following conditions are true:The computer has lots of physical RAM.The process loader lock is held by one thread.Multiple exceptions occur at the same time.In these conditions, several threads wait for the memory manager, and the program stops responding for several seconds.
