hello all
today we had another core on another kamailio instance, on different function, but also
seen something like a loop with the do_action and run_actions functions.

```
this indicates something like the process is busy with other messages?
On the 200OK that caused the segfault, we called rtpengine_manage jsut before execute
get_profile_size. It doesnt seem the rtpengine had any issue or was delaying the response
to other requets from kamailio.
Let me add the full backtrace
[core_mad_talos_1_btfull_26march2022.log](https://github.com/kamailio/kamail…
Please let me know if you might need something else
