Every so often, I'm seeing these two alarms appear in the WC.
The Data Service container process is running low on heap memory (> 90% utilized.)
followed by
Data Service is functioning properly.
They appear and go away within a minute or two every time. On the Data Service heap memory thing, I did review this KB VMware KB: ESXi/ESX host reports VMFS heap warnings when hosting virtual machines that collectively use 4 TB or 20 T…, but I can't modify the suggested parameters under VCSA 6. It says it's supposed to just do its job and grow as needed, but to continue to see these pop in and out is bothering me. It also seems to happen more frequently when a VM CPU usage alarm is triggered.
Does anyone think this is indicative of a bigger problem that I should be concerned about, or is this normal behavior to deal with the amount of activity on the instance? There are a lot of VMs in use and the datastore is always around 75% full, but CPU and RAM have been 50% or less. If abnormal, where should I begin to look for any signs of trouble? RAM capacity of the VCSA or some other config parameter(s) that might need to be tuned?
