I have a question regarding running Ubuntu 17.10 (with open-vm-tools) as a VM on ESXi. I installed ESXi on my PC then install Ubuntu 17.10 as my virtual machine. Below is a screenshot of my VM settings:

What my problem is, the ubuntu desktop will hang while:

1. Browsing some website using FireFox (I tried Chrome but same result). I'm not sure if that is randomly but I tried to restore all sessions, then desktop will hang again.
2. If I leave the machine idle, after a few hours the same will happen.
3. After this issue happens, even ping is not able to reach the VM.

Symptoms:

1. Cursor is working, but not able to click on anything.
2. The system clock is freezed on the hang time.
3. ping test to virtual machine will show not able to reach to host.

What I tried:

1. I tried to increase the total memory on VM settings, but it doesn't help.

2. I tried to cat the logs under /var/log/syslog but no luck, there is no error captured during that period. Please refer to below screenshot (I reboot the machine at 11AM).

   

Anyone knows more about this issue and how to solve it?
