Author: Henning Westerholt <h...@skalatan.de> Committer: Henning Westerholt <h...@skalatan.de> Date: 2019-12-19T17:44:19+01:00 dispatcher: fix bugs in ds_inactive threshold and ds_probing_mode 2 (GH #2100) - fix bugs in ds_inactive threshold and ds_probing_mode 2 (GH #2100) - ds_mode 2 should ping only gateways with mode inactive and probing - ds_inactive threshould should work also in ds_probing_mode 0 and 2 - move ping logic to a small helper function (cherry picked from commit ee45c2a07292cc977a7a212cac18fd2156279588) --- Modified: src/modules/dispatcher/dispatch.c --- Diff: https://github.com/kamailio/kamailio/commit/d9d677cbc30b2f771a3742c3aa95fd736dc48765.diff Patch: https://github.com/kamailio/kamailio/commit/d9d677cbc30b2f771a3742c3aa95fd736dc48765.patch --- diff --git a/src/modules/dispatcher/dispatch.c b/src/modules/dispatcher/dispatch.c index 18b713ce02..86b7ca1f1a 100644 --- a/src/modules/dispatcher/dispatch.c +++ b/src/modules/dispatcher/dispatch.c @@ -2737,6 +2737,10 @@ int ds_update_state(sip_msg_t *msg, int group, str *address, int state) if(idx->dlist[i].message_count < inactive_threshold) { /* Destination has not enough successful replies..
