Many errors logs should to be ignored

[zjg555543]

version

While useing Erigon rpc(v2.60.0-beta5) to connect data stream(v0.2.7).

issue

The rpc node always connect and stop the data stream by a single call.
https://github.com/0xPolygonHermez/cdk-erigon/blob/v2.60.0-beta5/zk/stages/stage_batches.go#L194

So, here is the data streamer's error logs. I think we can ignore this.
Hope to help.

I think this issue should be open in CKD-Erigon repo as it is result of how it uses the data streamer library.
