The McAfee drivers exhaust the kernel mode stack. The kernel mode stack is an important kernel mode resource. This can occur when many local variables are being defined in the functions and those variables are consuming a lot of memory off the stack.

To work around this issue, disable McAfee services, and then uninstall McAfee NetShield. For information about how to uninstall McAfee NetShield, contact McAfee Technical Support.
