Hi,
I noticed (while watching the logs more closely since updating to OpnSense 26.1 and now on 26.1_4) I saw those below notification errors:
(connection is fiber PPPoE)

Notice kernel [158] [fib_algo] inet.0 (radix4_lockless#948) rebuild_fd_flm: table rebuild failed
Notice kernel 158] [fib_algo] inet.0 setup_fd_instance: radix4_lockless algo instance setup failed, failures=22

Not sure if it is only 26.1x related. Systems runs, but others seeing this also and how to mitigate?
