I can see the below service hits counts on CSS11500. The load balance algorithm is defaulted to round robin. However, I still notice an uneven service hits counts in the pool. What could be the reason ? What does service hit counts mean. Is it just the number of hits or the active connections. If the connection is still active, would the service hits reflect that.

Also what is the difference between Total Local Connections, Total Connections, Current Connections and Load on 'show service' command.
From the CSS Content Load-Balancing Configuration Guide Ch11:
"If the CSS determines that a client is already stuck to a particular service, then the
CSS places the client request on that service, regardless of the load balancing
criteria specified by the matched content rule. If the CSS determines that the
client is not stuck to a particular service, it applies normal load balancing to the
You understanding is correct and round-robin is the default LB algorithm.
Once you bring stickiness into the picture then normal load-balancing algortihms no longer apply.
You need to consider the netmask on the advanced-balance statement (default 255.255.255.255), along with any NAT and proxy usage. The distribution of users across subnets will also make a difference.
What you're seeing is not entirely unexpected.
