Case: vSphere UI Health Alarm
Today I saw a warning in my vCenter: "vSphere UI Health Alarm". When I look into the vCenter Appliance Management, I can see that there is a warning at the VMware vSphere Client service. It says: "The server is running low on heap memory (>90% utilized.)".
Can anybody help to solve this?
Thanks a lot.
