OpsCenter drops connection to Masters

Hi All,

Need suggestions on possible root causes:

System:

Windows 2008 R2 Standard running OpsCenter Analytics v7.5.0.7

Running on a VM with 8 vCPUs and 32GB of RAM

The CPUs are almost all the time at 100%, caused by the  dbsrv11.exe process. At least, once or twice a week, we log in and find that all Master Servers (14) are disconnected, prompting us to restart OpsCenter.

Any suggestions?

thanks.
