Least Connections is only concerned with the current connection count between the big-ip and the server, not whether the server is serving traffic. If the pool member is up and it's his turn for a connection (i.e. currently has the least number of connections) it gets one.
One reason why a pool member would receive most of the connections is if it went offline for a period, once it was back online it would have potentially far fewer current connections, in comparison to the other pool members. This member would then receive the necessary amount of subsequent connections before parity with the others was achieved.
Least connections doesn't take into account what other traffic the pool member is serving, rather only connections from the VS specifically.
Hope the above is all correct and useful info?
