In a rare condition after providing afm, we get a tmm core. You will see the following line in avrd.log /usr/bin/avrinstall -c20 -t10 -s2401000 --provisionAVR=0 --provisionASM=0 --provisionAFM=0 --provisionPBD=0 --provisionAPM=0 --provisionFPS=0 --provisionPEM=0 --provisionVCMP=0
Traffic disrupted while tmm restarts.
AFM provisioned. Attack started.
There is no workaround at this time.
We check that the shared memory was allocated correctly before reporting on an attack.
