Cisco ASA loop broadcast packet

I have small office where running cisco ASA ASA5506 and version 9.4(1)
and it's also configured for IPsec VPN tunnel, My LAN subnet is 10.1.1.0/24

So i have found very interesting things in LAN where if i ping 10.1.1.255
(broadcast address) it create nuclear reaction and my packet goes in loop and fill my LAN with traffic and my cisco ASA CPU goes 100%

This is how i stop strom, clearing conn in ASA

ASA# clear conn address <source_address_of_desktop> 

I believe cisco ASA participating to amplify this storm. here is the basic config snippets of ASA

same-security-traffic permit inter-interface same-security-traffic permit intra-interface 

Notes: I believe one of above option has something to do with this storm.
