      When multiple threads run the BPMN flowchart at the same time, the sdncadapter of a thread waits for the return result of calling sdnc. When the return result of sdnc is associated with the BPMN graph, a deadlock occurs. The method of deadlock is org.camunda.bpm.engine.impl.messagecorrelationbuilderimpl.correlatewithresult.

      I use the "show engine InnoDB status \ g;" command to check the status of MariaDB cluster database. I found a foreign key constraint error, which is "foreign key constraint failures for table campabmn. act_ru_execution: constraint" act_fk_exe_promote "foreign key (proc_insert_id_) references act_execution (id_) on delete cascade on update cascade"

       In the list of questions, there are similar questions. The codes are cam-6468 and cam-3318
