The peer closes the connection before the SSL handshake completes. For more information take tcpdump and see if any unusual behaviour

Hi Samir ,

 

This was one time issue between specified time , So except SSL handshake logs we do see any other abnormality .

 

When you say peer closes the connection , Do you mean F5 << >> Pool member connection ? , In this case also VIP and pool members where not down .
