I have my exchange running on a virtual machine. All roles are running off this vm. After I've installed CU3 and taken it from 10 GB memory to 12 GB and gave it 8 vCPU from 4vCPU, the amount of memory it's paging seems to have gone from around 30% to 60%. The page file size is the memory size + 10 MB. There's about 120 users and 5 databases
I'm also getting this error, which I never got before any upgrades:
