Re: [SR-Users] Race conditions upon quick reinvite

Hello, this should give you some ideas, e.g. just adding a sight delay to the Re-INVITE In Kamailio. https://datatracker.ietf.org/doc/html/rfc5407#section-3.1.4 Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of David VILLAUME Sent: Tuesday, August 24, 2021 3:12 PM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Subject: [SR-Users] Race conditions upon quick reinvite Hello, We encounter sometimes reinvite from some provider really quickly after 200 OK ACK so sometime there a race conditions where the re-invite exits Kamailio before the ACK leading to some Freeswitch “500 Overlapping Requests”. [cid:image001.png@01D798FD.2A666360] I tried to catch the 500 on failure-route unsuccessfully as transaction is already established. Do you have any idea on how I could deal with this behavour ? Running 5.3.6 with 8 childs modules used :(tm + dialog) No costly action performed on ack that can explain slowliness. Regards, David
