  I have tested and found that the kernel 4.19.32 may not have this problem,the problem in kernel 5.0.5 is obvious.
  Under the kernel with this problem, I found a way, if the problem occurs, run the following command immediately under the appropriate permissions:

        sync && echo 3 > /proc/sys/vm/drop_caches && sync && echo 3 > /proc/sys/vm/drop_caches && sync && echo 3 > /proc/sys/vm/drop_caches

  This may reset some of the system's operations, which may affect the next few seconds of IO operation, but should alleviate the unresponsive situation.
