3CX VM is freezing up

[JST]

In the last week, I found my 3CX system in an unresponsive state multiple times. Oddly, enough it always seems to stop working at night time and it acts like the whole VM got "paused". It literally stops working from one minute to another and when it happens there is no network or log activity. It simply stops responding to anything. I mean it still shows the logon screen when I am trying to connect using the built-in VMware feature to connect to the machine, but it no longer responds to any keyboard entry.

I must say that I am stunned. I have never encountered similar behavior by a VMware machine. It should also be noted that the same VMware host is running another 5 VMs without any issues.

Any ideas on what could be wrong?

Hello @JST

Is it the whole vm machine that gets stuck or just the PBX? Do you have to restart the VM to get it responding again or does it come back up after some time?

Gents,

I just wanted to confirm, that we had exactly the same issue, described by JST (!!)
This led to the situation that we (as service provider) failed on the SLA !

In contrast to the situation described by JST, our 3CX VM exclusively runs on the ESXi v6.x - ie without other VMs (...)

In order to operate the 3CX in a professional environment, we would highly appreciate if the PBX would provide adequate monitoring capabilities (SNMP, etc.).
