SYMPTOMS
When you are running server-to-server shadowing with Windows NT 4.0 and Citrix, non-paged pool memory may leak and eventually generate a &quot;STOP 0x00000041&quot; error message on a blue screen. This problem is compounded when the shadowing session is performing intensive graphical functions.



CAUSE
Non-paged pool memory is being allocated but not freed by the Tdpipe.sys driver. The pool tag for the pool that is being allocated is Mdl.
