We are running 3CX in production on a Windows Server 2016 Standard edition virtualized on a VMWare ESXi host. It's for around 40 extensions and the VM has 8GB of RAM and 4vCPUs. Performance is fine but the system itself is quite unstable with almost one freeze per week. 3CX is the only thing running on an otherwise fresh Windows Server 2016 install. Is there anything we can look into? Any 3CX debug logs that might be helpful? What happens is that the entire VM becomes unresponsive and only a hard reboot via VCenter helps. Then it works fine again for around a week until it hangs again. Are there any memory settings we could tweak? Or anything else we should optimize?
