Globally enabling TiFlash and TiDB storage engines results in the following error when executing SQL:
ERROR 1105 (HY000): other error for mpp stream: From MPPquery:441050903959044097:4,task: Code: 0, e.displayText() = DB::Exception: write to tunnel which is already closed, Receiver cancelled, reason: Push mpp packet failed. Receiver state: CLOSED, e.what() = DB::Exception,

Does the corresponding table have a TiFlash replica? What is the status of the TiFlash node?

| username: wenyi | Original post link

Yes, and the status is normal. The first query is very fast and returns results normally. When querying the second time, this error is reported.

The issue was said to be resolved in the minor version 5.4, why does it still exist in version 6.5.1?

I don’t use TiFlash…
