[SR-Users] Core dump on diameter CCR request

[Mojtaba]

Hello,
We developed OCS based on these module in Kamailio: ims_charging,
ims_ocs, ims_dimameter_server and worker process written in Q_HSS. We
have not this issue.
Are you sure ims_charging is connected to any ocs proccess like ims_ocs?
Because CCR/CCA and other related message is transfered between them.
With Regards.
