[SR-Users] Race conditions upon quick reinvite

[Daniel-Constantin Mierla]

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
