HTTA-601 — RADIUS state does not fit into the session table entry
If RADIUS challenge/response authentication is used, the RADIUS server sends back a state information together with the challenge. This state must be passed to RADIUS together with the response. The state information must be stored in the session table until the user sends a response to the challenge. There is a fixed-size place for this information in each record of the session table. If the state does not fit into this place, the request processing fails. The solution is either to reconfigure RADIUS to use smaller state, or to change RAD_STATE_SZ in mod-aproxy.h and recompile the proxy.
