linux redhat + hung + reason for hung

1

I have linux redhat machine - 6.8

and from the /var/log/message file I see the following lines:

from my point is seems that linux is hung because the bad connection to the server - 100.1.93.7 ,

is it correct ?

That could be just coincidence
Your real issue is this

INFO: task oracle:16131 blocked for more than 120 seconds

So you should check your Oracle alert log file.
