Hi, It has been observed that whenever we are running security scans on our website which is hosted in DNN7.4.1 version, Application Started and Web Server Updated event starts getting logged very frequently. This impacts the performance of the site, application is recompiled and site becomes very slow. Around 20-30seconds to get warmed up again. Can this be a memory issue? A thread issue? An application pool configuration issue?
Our site is hosted on 4 web servers with load balancer for distributing load. Memory threshold is set to infinite but there are other apps also hosted on the server. During security scans , CPU utilization usually spikes to 100% and app domain keeps on crashing.
