[SR-Users] Race conditions upon quick reinvite

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.
