without any details its hard to know. Are there any alarms regarding CPU utilization / Disk usage? Is the hypervisor overprovisioned? Also, this is not a zone director but rather smartzone. And if you have support issues, you should have a support contract and open a ticket. The forum is mostly run by other users who volunteer their time.

The main cause may be ntp synchronization problems.

Check ntp on VM hypservisor wherther it's same as current time or not.

Not sure which hypervisor you're using ... But at least it doesn't look like hyperv / azure / aws / google / VMware. Also, for some reason you're emulating two numa nodes (2 sockets / 4 cores per socket). Shouldn't make a difference but weird it got configured like that.

I assume the disk is on SSDs?

Is the underlying HV kvm?

Hi Diego

Our client is insisting that we install the VMTOOLS for the betterment of performance of the VM but you said before that it is a closed appliance and there's no need to install VMTOOLS

Here is the question of our client:

"We cant adjust more memory allocation. I suggest is install the vmtools to automatically adjust itself. In additional, vmtools is to enhance performance and stability of vm.

Please send a letter why you don’t want to install vmtools or why we need to adjust more memory allocation? Give a figure example 1GB RAM how many users can accommodate?"

Thank you.
