Hello Mr.Chu.
After experimenting with monitoring DB myself, I have figured out a
minimal reproducable test case, I am afraid that the issue still shows
up in 2.4.39 (distributed by SUSE Server 12).
The 2.4.40 changelog does not seem to suggest any relevant bug fix, but
I will give it a try anyway.
May I help by attaching the test case? Which Linux distribution would
you like to use for testing?
Thanks very much.
Kind regards,
