(e.g. has a list with rtpengine urls but those are not reachable) Recently had a crash similar to #3297, but in an outdated kamailio version (5.5.7). Tried to reproduce this in 5.5.7 and 5.8.3 but could not crash any of them. However I managed to get the logs similar to ones right before the crash happened: ``` 2024-10-04T17:39:58.026206+03:00 kamailio[450237]: ERROR: {1 1 INVITE 203-450290(a)192.168.100.93} <core> [core/action.c:1595]: run_actions(): alert - action [corefunc (16)] cfg [/home/stefan/kamailio.cfg:625] took too long [29310906 us] ``` ...directly related to how much rtpengine_manage() function took to execute. So routing of SIP is delayed by that ammount. Tracked this in code, down to where this lock is get, when "aggressive_redetection" modparam is enabled: https://github.com/kamailio/kamailio/blob/66fe6eb71e58a02222d1a2fb00f9a0cdb… I will double check that part of the code, since I don't think a lock get is necessary. It only updates a value inside a node, inside the list of nodes, but not changes the list links at all. (this in another PR) For now I propose to disable this aggressive_redetection mechanism by default. Since it delays the SIP routing logic when no rtpengines available (and in some cases lead to crashes in transaction module).
