Dear Horiguchi-san, Thank you for making a patch! They can pass ci. I'm still not sure what should be, but I can respond a part.

This was introduced in 6bcce2580 to ensure waiting more than 2 seconds. I've tested on my CI and found that removing the sleep can trigger the failure. Also, I confirmed your patch fixes the problem. PSA the small patch for cfbot. 0001 and 0002 were not changed. Best Regards, Hayato Kuroda FUJITSU LIMITED
