Hi all,
I want to give update....
Removing auditd didn't solve the problem. Still hang.

So, finally I create a cronjob to echo date and time into a text file
every 5 minutes to find out if there is a pattern on when the hang
occurs and the result is ........
It hasn't hang for more than 3 days...!

Definitely there is still problem, but somehow that cronjob prevents
the hang from occurring. Like as if the VM got idle, it will hang?
I don't know...
