Device intermittently reboots while processing encrypted rtp (srtp udp data) packets during normal operation. The event generate a system report with a qfp-ucode core inside it.
There are encrypted rtp configuration on the device such as: dial-peer voice 102 voip preference 1 destination-pattern [40]... session protocol sipv2 session target ipv4:X.X.X.X:xxxx session transport tcp tls voice-class codec 1 voice-class sip srtp negotiate cisco voice-class sip options-keepalive retry 3 dtmf-relay rtp-nte srtp fallback no vad
Remove encryption configuration for rtp traffic. Do not use srtp udp data packets. Change the configuration to simple rtp data packets.
This issue is presented due to the improper handle of the crypto voice traffic at software level where two data plane threads are trying to delete the same packet during a race condition.This is a corner condition but it also required the presence of crypto voice traffic configuration. If suspecting this issue, consider to collect "show tech" from the affected device as well as the "system report" files inside the core/ folder on the bootflash/harddisk.
