Can someone tell me what "Current load average" is?

We have a 2 node HA cluster, each box is a dual hexa-core 8GB RAM system. Dashboard graphs show CPU at 17%, RAM at 27%, but in the HA live log I see these warnings: 
2011:10:27-00:03:16 secgate-an-2 ha_daemon[6011]: id="38A1" severity="warn" sys="System" sub="ha" name="Current load average 12.58 is high!"

2011:10:27-00:03:17 secgate-an-1 ha_daemon[5977]: id="38A1" severity="warn" sys="System" sub="ha" name="Current load average 12.58 of node 2 is high, please check you system!"

    And what processes are causing this high load?

    What is your "normal" network throughput?

    It looks like httpproxy and postgres.  We are a large community college and push 10's of thousands of connections through during the fall/spring terms.

    Here is current connections graph


    and here is the traffic report:


    I notice when viewing top stats that I always only see one instance of the httpproxy process but see 2 or 3 postgres processes, can't the httpproxy utilize sms to have multiple instances of the httpproxy? This is with Irix mode turned off.
