In my case happens during attacks.
I use cisco ASDM to see connections or show connections using CLI.
I use these tools in order to find repeated entries.
Sometimes I foud a lot of connections from a single IP.
In others cases I found a lot of connections from many IPs destinated to the same port.
In this case I use ACL to block unwanted traffic.
Enable also IP audit feature in order to block some well know attacks.
Regards.
