工作流审核到最后一步迟迟不能完成

 select*from act_hi_actinst  WHERE PROC_INST_ID_='870391';
 select*from act_hi_comment WHERE PROC_INST_ID_='870391';
 select*from act_hi_identitylink WHERE PROC_INST_ID_='870391';
  select*from act_hi_procinst WHERE PROC_INST_ID_='870391';-- 没有结束数据
  select*from act_hi_taskinst  WHERE  PROC_INST_ID_='870391';
 select*from act_hi_varinst  WHERE  PROC_INST_ID_='870391';
 select*from act_ru_task WHERE  PROC_INST_ID_='870391';-- CREATE_TIME_>='    2019-03-15';
 select*from  act_ru_variable WHERE EXECUTION_ID_='870391';

流程看了步骤没问题。
