You might need to add virtual memory to keep the vRealize Operations Manager process running.
When the vRealize Operations Manager virtual machine requests more memory than is available, the Linux kernel might kill the
vcops-analytics process, and the product might become unresponsive. If that happens, use the reservation feature in vSphere to specify the guaranteed minimum memory allocation for vRealize Operations Manager virtual machines.
- In the vSphere Client inventory, right-click the vRealize Operations Manager virtual machine and select Edit Settings.
- Click the Resources tab, and select Memory.
- Use the Reservation option to allocate more memory.
