Hello,

I got some time Ack packets looping on my servers during 4 hours if I don’t restart the system ( 4 hours is my dialog timeout).

Jan 27 16:59:02 vma-2 kamailio[4544]: WARNING: { 1 # SDvl91b03-576e9e12b1569f0361fceb3625955037-agvh8j0020 * } dialog [dlg_handlers.c:1322]: dlg_onroute(): unable to find dialog for ACK with route param 'dc2.f24' [717:1071] and call-id 'SDvl91b03-576e9e12b1569f0361fceb3625955037-agvh8j0020'

It generates approximatively 2 millions packets per loop.

On the last occurrence I noticed a ‘SIP/2.0 200 canceling’ generated per Kamailio before the loop started (which seems uncomon on this host)

Bellow is a screenshot of the beginning of the loop and may dialog and topos config.

Has anyone encountered such behavour ?

Regards,

David
