Loss of transaction tracing data post v1.4.0 #802
Description
System information
Erigon version: erigon/1.4.1/linux-amd64/go1.24.9
Chain/Network: Mainnet
Behaviour
After we upgraded to v1.4.0, we discovered a couple of random nodes in the pool has lost tx tracing data. Transaction and block data exists on the node, and there is no pruning process. After upgrade at a specific block number, then all trace_transaction returns null on newer transaction post the upgrade. Historical transactions are still trace-able. Only impact on new transactions post the upgrade.
We will need to resync the nodes. I was just surfacing this issue for awareness. Currently nodes are on v1.4.1, but the lost transaction trace data are permanently unavailable unless to resync.
