BoPDRPC      = NewConfig("pdRPC", &metrics.BackoffHistogramPD, NewBackoffFnCfg(500, 3000, EqualJitter), tikverr.NewErrPDServerTimeout(""))

No error message for PD server timeout.

BoPDRPC      = NewConfig("pdRPC", &metrics.BackoffHistogramPD, NewBackoffFnCfg(500, 3000, EqualJitter), tikverr.NewErrPDServerTimeout(""))

No error message for PD server timeout.

I think it is not caused by PD server timeout. The error for PD server timeout in tikv-client should be converted to a normal PD error for tidb in driver and it have its special error code 9001

By the way, @vivid392845427 could you provide the log of tidb/pd/tikv?

According to the log of tidb, it is a bug caused by that the driver does not convert the tikv.err to tidb.err in function tidb/store/copr/region_cache.go:65
