0 IIS Worker Process using 95%-100% of CPU 1 Don Smallman posted 8 Years Ago Hi,I was making some updates to a calendar and registration when my site just froze up and went down. I was not sure if it was something I did or not.I logged on to our server and noticed that the IIS Worker Process was using 95%-100% of CPU. Further investigation shows that it is the Default App Pool that is using these resources.Does anyone know what would be causing this and why it would just start happening out of the blue? Out site is basically down because the resources are all used up. Also the memory usage keeps climbing the longer I let IIS run. It is up to almost 1.5 GB at the moment.Any help is appreciated.Thanks!Don Smllman
