Hello, Vladimir Thank you for your reply. Since we have not confirmed until verbose is enabled, it is unknown at which timing it is output. However, it confirms that it is output 10 minutes after Service start. Do I need to do something? Thanks.

Is this a configuration issue in this case? Or is it a known bug? It's not known, and it's most likely unrelated to reorder_RR.  I expect it's some edge case not handled well in predict.lua, though I can't immediately see how the error might happen. --Vladimir

Hello, Yes, it does not seem to have problems with the behavior of Prefetch etc. It seems that no trouble etc has appeared in other parts. Thanks.

(Even though prefetching probably stopped.)
