Hi,
We have CUCM 5.1.2 in our setup with one publisher and two subscribers. Now a days whenever we login or whenever we are opening any page in Admin window it takes long time and most of the time it doesnt open, it says " Loading please please wait". I have attached the screenshot for the same.
I have tried restarting tomcat as well as server also but no luck. Same issue with CDR admin tool also.
