Free Radius + Captive Portal No valid RADIUS responses received

  • Hi guys  :)

    My Captiveportal shows very strange behavior. Occasionally (2-3 times in 5-6 days) it returns standard php error about exhausted allowed memory size. Logs says that in this moment FreeRadius does not answer

    Error sending request: No valid RADIUS responses received

    That is why captiveportal does not work. Why this happens?

    This error disappear if I restart FreeRadius and Captiveportal.

    My installation is Pfsense 2.1-RELEASE (amd64),
    Memory 2 Gb
    FreeRadius + Mysql +Captiveportal

    Average users per day : 6-8 not much

    Please, any ideas?  :-[
