Currently the counter of tt_local_entry structures (tt_local_num) is incremented each time the tt_local_reset_flags() is invoked causing the node to send wrong TT_REPONSE packets containing a copy of non-initialised memory thus corrupting other nodes global translation table and making higher level communication impossible.
