We were doing web site performance capacity testing using a virtual server on a f5 Big-IP 1600 with 2 node back end, SSL pass through, round-robin algorithm, auto SNAT, using synthetic load generator. The default "Connection Limit" values for the virtual server, pool and nodes were found to be 0 but that appears to be a default connection limit of 200 before the software load generator reported dropped connection attempts so the default 0 value definitely not mean unlimited.
