Dear Erman sir,

I am facing a issue for last few days that our test ebs application 12.2.12 are going down immediately , make sure it is a VM in ODA server.

The issue is started 10 days ago after my Network Administrator are inform me that there is an malicious activity are happening in my test server . he has blocked ssh 22 port, so no body can access this server.

One more thing i notice that if i used top command, there is one process kauditd0 are occuping 90% cpu resource, even i killed this process again the new process is appeared.

Below is the output of top command.
