Make sure that you have set high value for max_allowed_packet and interactive_timeout variable.
Prefarably set 16/32MB for max_allowed_packet and 28800 seconds (8 hours) for interactive_timeout

increased net_read_timeout value to 60 on mysql and also increased the timeout and maxconn values of haproxy on web-servers to access mysql master-slave server. I can't see a single abort_connections in mysql after increasing those values. max_allowed_packets are already set to 64M. Will update you if the issue occurs again.
