Symptom
The last reload reason shows Critical process qfp_ucode_utah fault on fp_0_0 (rc=139).
First time documented was in ISR4331-DC/K9 with Version 17.09.02a but it may happen in previous codes or none fixed releases.
This event generates a system report with a core file inside.
Conditions
Happen during normal operations.
Unexpected reload happens when a malformed packet is tried to be processed. When the device is not able to determine the kind of packet the device crashes. There will be added in the fix a mechanism to discard that kind of packets before try to process them.
Workaround
Not work around by the moment, still in review.
