Hi, I am using the free radius 2.1.3. I have a module rlm_xxx and have initialized it as thread safe. I have configured the start_servers as 3. The issue I am having is as follows. I see that a new instance is getting created when the first one is busy handling a request. (I do this this by adding a sleep in the module and printing the threadid) I am expecting the xxx_instantiate function to get called each time a new instance is created (reading in the documentation). This does not happen. I am actually connecting to a server in the instantiate function and storing the socket id in the *instance, so that I can use it later in the authenticate etc. But it seems that the socket id is the same for all the instances. *instance seems to be shared by all the instances ?? Am I missing something/configuration, your help is grately appreciated. Thanks in advance for your inputs. Thanks, Latha.
