ColdFusion2016 services are not getting started

ColdFusion2016 services are not getting started, It was running since last year now they are stopped suddenly, while I'm checking the cf-out logs it says 

"Either the server is already running or some other application is using the HTTP port"

CF-Error logs says "failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak."

I have checked no other application is using it except coldFusion.

When I stop IIS site then ColdFusion services gets started.

Can any one help me here.
