[SR-Users] Processes blocking - troubleshooting slow actions

[Julien Chavanton]

I guess action type 16 IF_T is accounting for the entire scope block since
it is recursive.

I wonder why var assignment in the main route scope would do the same :

2019-11-13T21:58:04.018631614Z 23(42) WARNING: <core> [core/action.c:1586]:
run_actions(): alert - action [corefunc (16)] cfg
[/etc/kamailio/kamailio.cfg:115] took too long [2579486 us]
$var(reply) = 0; // I wonder how this can endup blocking ?
