Hi Thibault,
have you tried last tsilo code from 4.3.x branch?
Recently there has been a fix (
https://github.com/kamailio/kamailio/commit/6ce6803d57dabe287d7d6fa859e93c1df402d821)
for an issue that may be related to yours.
I'll keep investigating to see if I can spot something else. In the
meanwhile could you describe your scenario? Are you storing multiple
transactions per ruri? Did any of them got a final reply before the crash?
Regards,
Federico
