What can be causing this issue? Our CPU of VC is showing 100% with a lot of free memory. The wireless test at location is still fast but this does seem to effect ability to get into VC to manage it. We upgraded firmware to 6.4.2.3-4.1.1.2_48114 one week ago that is only change. We went back in firmware at some locations and that seemed to fix this for most part. Does anyone have any other fixes instead of down grading firmware?
