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.
