I have a AX4-5 that acts as the shared storage for a Windows Server 2008 file cluster. The issue I am facing is that which ever node the SAN is attached to seems to display the symptoms of a memory leak. I have been working with Dell on the situation and they have been focusing on the iansw60e.sys driver. This is the NIC teaming driver for the Intel Gigabit VT Quad Port Server Adapter. Has anyone seen anything like this before?
