need help!

I have a question about tdi_fw.

It seems that there are memory leaks in tdi-fw.

I checked memory usage by using verifier.exe(windows tool).
The amount of NonPagedPoolUsageInBytes is keep increasing.

Is there any problem in tdi_create and tdi_cleanup routine?

Do you have any idea or suggestion?

What’s the reason of this problem and how can i solve this problem?

Thanks in advance.
