What operation triggered it?

Didn’t do much, just had some SQL running in the background, and the computations are quite complex.

Based on this error, the cause is not clear. We need to look at the earliest error information, check the logs of the KV nodes, and also look at the IOPS on the monitoring page.

Sometimes certain complex SQL queries do have some bugs. If errors occur multiple times, you can observe for commonalities.
