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...
