Packet drops in the IPsec Tunnel between Cisco ASA firewalls

Hi ,
I am facing connectivity issue through the IPsec tunnel configured between Cisco ASA firewalls. Pls help & suggest the way forward to troubleshoot it.

Scenario: The IPsec tunnel (Ikev1) was stable since years but suddenly started observing random packet drops between the interesting traffic only. There are no packet drops to the remote peer public IP address at the same time ?
