--------------------------------

Hi, [~cdutz], [~julian.feinauer]. Thank you very much for your reply. this 
program based on springboot and plc4j 0.8.0,  may be it is my program bug. I 
haven't mastered the skill of use springboot yet. another program for the same 
situation based on maven and plc4j 0.7.0, performing better. runing more than 
one month on the test computer without any error.
Thank you very much again.
