Hello,
see if setting this core parameter helps:
* https://www.kamailio.org/wiki/cookbooks/5.5.x/core#route_locks_size
An alternative would be to use htable to store the time when the 200ok (or ACK) is processed and if the re-INVITE comes very fast, do a sleep()/usleep().
Cheers,
Daniel

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”.

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
