View products that this article applies to.

Symptoms

This issue occurs when you make a major change to a Lync topology (for example, adding or removing a server) and then you publish the topology in a Microsoft Skype for Business Server 2015 environment that has the Response Group Service run.

When this issue occurs, the LyncIntFeature or LyncExtFeature application pool on the Skype for Business Server 2015 front-end server consumes large amounts of CPU resources.
