  That's "NO eap session matching..."

  Then your supplicant and/or access point is broken.  If the supplicant
loses association with the AP, then EAP *must* be re-started from
scratch.  Re-using State attributes from previous EAP sessions will
cause authentication to fail on *every* single RADIUS server that exists.

  No.  EAP requires state.  The AP maintains state for EAP sessions.

  Fix the AP so that it doesn't re-use old State attributes.
