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
