You are only allowing two hosts to ping each other. This will also deny all other traffic as the implicit deny any any will kick in.
Pls. remove these two lines below
access-group inside_access_in in interface inside
access-group dmz3_access_in in interface dmz3
and try the ping again. Make sure to source the ping from the inside interface or from a high security to a low security interface. You do have icmp inspection enabled and the replies should will be automatically allowed.
