What's the meaning of log line "Server State transition from INACTIVE to INTER" ?

I run Web Agent and I have set the traces to show the statistics about connections to Policy Server.
I see line like this one :

[09/28/2016][13:38:11][13:38:11.253][19415][1709545792][SmClient.cpp:1825][CSmServerHandle::StateTransition][][mywebagent.mydomain.com][44443][][][][]
 [Server State transition from INACTIVE to INTER]

What's the meaning of INACTIVE and INTER ?

These key words are used to give the status of a Web Agent process and its connections.
