Hi,

On Windows Server 2016 version 1607, I encountered a memory leak issue with IP Helper Service. It's memory usage grow to 200+MB in two weeks time, and could go up to 1+GB in months.

After enabling tracing for IpHlpSvc I found following messages in the log:

......
[4468] 06:53:06: Couldn't get static port mapping collection (hr 0x00000000, collection 0x0000000000000000), will retry after 1500 ms (1500 total remaining).
[4468] 06:53:07: get_StaticPortMappingCollection for UPnP failed (hr 0x00000000, collection 0x0000000000000000).
......
[2628] 06:53:11: IpTlsObtainGpKeyHandle failed: Status = 2
[2628] 06:53:11: IpTlsObtainGpKeyHandle failed: Status = 2


Is this an known issue? Is there any hot fix for this?

Thanks.
