We have a 340 ADC.  We've set up a HTTPS service with 6 real servers.  The load balancing algorithm is Weighted Least Requests and Session Persistence is Source IP with a netmask of 255.255.255.255.  Each real server has an identical weight of 1. 

 

Real server 1 always gets a lot more connections than the other real servers (50-60 connections when the other servers have 0-3 connections).  We've examined our connection logs and we're not seeing lots of connections from a single source IP - lots of different source IPs are being sent to real server 1. 

 

In normal operation this doesn't cause a problem but in periods of high traffic server 1 gets swamped while the other servers are doing relatively little.  Does anyone have any suggestions what we might be able to do to rectify this?

Correction - it’s a 540 ADC, not a 340.
