Aiccu Memory Leak in Win2k3

I'm running Windows Server 2003 X86 SP2. Tunnel connectivity works and I can access/ping IPv6 enabled sites using the AYIYA protocol. So far so good. The problem is that I get insufficient resources errors as soon as there is high data flow on the tunnel tap device (approx. after 30-45 minutes) --> Server shares and the tunnel become immediately inaccessible. This leads into "The server was unable to allocate from the system nonpaged pool because the pool was empty." system errors in the Windows Event Viewer (ID 2019). I audited the aiccu-console process and it's consumption in the paged- and non-paged pool:
the np pool size stays static at 3k
the paged pool size rises approx. 16k per sec -> approx. 40megs in the paged pool tab when the described errors occur. The tunnel connection stays active btw, but there is no pinging/tracerouting possible after reaching this point. I tried the different tuntap device drivers v8/v9 and latest OpenVPN, but the failure remains the same. I hope there is a way to fix this...

After further investigation using Process Explorer it seems that despite the information given in Task Manager the overload of the Non-Paged Pool is causing the failure. The NP-limit on my system is set to 260megs. The errors occur immediately after the 250meg mark is reached (--> caused by the the aiccu-win-console process). The size of the Paged Pool is not rising as much when running the aiccu-windows-console.exe according to the information displayed in Process Explorer and so I guess a Paged Pool overload can be excluded. No one experiences the same behaviour in Server 2003?

I'm surprised nobody has noticed this since your initial report. Just started running AICCU on Windows XP and it has a horrific non-paged pool memory leak. Download a few hundred meg and first Process Explores crashes, then the system crashes. Task Manager show the NP pool leak clear as day.
I've run the same tap/tun driver with OpenVPN for probably ten machine-years on Windows 2003 (32-bit) and have not seen this issue before, so it might be related to something AICCU does or to a AICCU-only kernel driver. Or, perhaps it's a Microsoft bug in their IPv6 code. Not likely the latter would ever be fixed. Has anyone dug into the former possibility?

I'm experiencing exactly the same.
Any update on this?
