Oversized Vector Allocation

I am seeing this on electrs-esplora 0.4.1. Indexing is stuck and is falling further behind.

I think it should be resolved by Blockstream/electrs@93fff34, which is included by 7bc4c7d.

Confirmed. Updating to latest version (esplora:latest) resolved the issue. Thanks, @romanz!
