Maapi socket attach


we are working with external DB.
I am trying to receive a callback on validation point, after registration during init using confd_register_trans_validate_cb, confd_register_valpoint_cb.
when execute “commit check” the validation init callback is called, but then there is timeout when confd tries to call again. the init validation transaction call: maapi_attach and confd_trans_set_fd.
I understand that the validate callback should be called via the mappi socket, according to the attached details.
the confd_devel.log does not have relevant infor/error.
can you guide me what can be the reason for that?

Problem resolved. thanks
