2008 R2 Domain controllers svchost has between 60 - 80'000 handles, memory leak??
Posted on 2014-02-05
Hi All
We have been having intermittent issues with authentication for the last few days and I have been digging deeper into the domain controllers.
I have noticed on two of the DC's the handle count for svchost -k DcomLaunch are between 60 - 80'000 on each DC, this seems overly high.
Looking at the services on Sysinternals process Explorer tab I see this is responsible for DcomLaunch, PlugPlay and Power.
Where do I go from here to determine actually what is causing this high number.
Thanks

If it is the memory leak issue , I recommand you to use RAMMAP sysinternal tool.
It exactly shows what is consuming more memory. It might so happen that , some processes don't release the memory . You need to identify those and see the web to get the resoultion or apply hot fixes for those.
See if below link help you
