SYMPTOMS
Consider the following scenario:
- You are running a Windows Server 2003-based computer under a heavy load.
- The Storport driver is being used.
- The Emulex elxstor driver is installed on the computer.
In this scenario, the computer stops responding.
In a typical instance of this problem, Microsoft SQL Server is installed on the computer. In this situation, the following message is logged in the SQL Server Errorlog file:
CAUSE
If the device queue is paused, the Storport.sys driver may cause a miniport driver to leak memory for each I/O request. This leaked memory accumulates very quickly, and eventually the computer stops responding.
