ok, I have looked at Why do Asp.net timers/updatepanels leak memory in Chrome and can it be fixed/worked around? and Unbind Events in ASP UpdatePanel BEFORE Ajax Request to prevent Memory Leak.
I have inherited an ASP.NET intranet site that updates with live data using update panels. Within 10 minutes of opening this site in Chrome, the Chrome instance's Memory usage on the client (not the server) will be sitting at ~1.5 GB.

But as of yet, I have not found a good fix/workaround for this.... I will admit that I am kind of an amateur when it comes to ASP.
