rtpengine version the issue has been seen with

14.1.1.4+0~mr14.1.1.4-1.el9

Used distribution and its version

Distributor ID: AlmaLinux Description: AlmaLinux 9.7 (Moss Jungle Cat) Release: 9.7 Codename: Moss Jungle Cat

Linux kernel version used

5.14.0-611.20.1.el9_7.x86_64

CPU architecture issue was seen on (see uname -m)

x86_64

Expected behaviour you didn't see

No response

Unexpected behaviour you saw

A single call got stuck in an infinite loop producing a log flood of over 70,000 lines per second of "Kernelizing media stream...". This state stalled the Userspace process, causing SIP control commands to hang for 38 seconds until the loop was aborted due to "Too many packets in UDP receive queue"

The "Kernelizing media stream..." log message alternate between
"Kernelizing media stream: remote A -> local B"
"Kernelizing media stream: A -> B | C -> D"

Steps to reproduce the problem

I have been unable to reproduce this intentionally; This issue occurred for a single call in several million.

Additional program output to the terminal or logs illustrating the issue
