electrs stops when looking up for addresses with a lot of transactions

[tchjntr]

Describe the bug
I am running a self-hosted instance of Mempool and I stumbled upon an address that has quite a large number of transactions.

When looking up for that address on my self-hosted Mempool with a Bitcoin Knots + electrs backend, electrs stops working with the following error messages:

The command bitcoin-cli getblock 00000000000000000000b71ed0d9bec536d4fbbfa4da8dece0edb25324d11db0 is successful so it's not an issue with a possible missing block.

Electrs version
0.10.5

To Reproduce
Steps to reproduce the behavior:

1. Fully synced Bitcoin Knots and electrs
2. Configure and run self-hosted instance of Mempool
3. Lookup address bc1qm34lsc65zpw79lxes69zkqmk6ee3ewf0j77s3h
4. electrs system unit stops

Expected behavior
I expect address lookups to complete successfully

Configuration
electrs config file:

db_dir = "/home/janitor/.electrs/"
db_log_dir = "/home/janitor/.electrs/"
daemon_dir = "/home/janitor/.bitcoin/"
cookie_file = "/home/janitor/.bitcoin/.cookie"

monitoring_addr = "127.0.0.1:4224"
wait_duration_secs = 10
jsonrpc_timeout_secs = 15
index_batch_size = 10
index_lookup_limit = 0

System running electrs

• Deployment method: manual, static linking

I have the same log messages. This is probably the same bug as #1011

This is easy reproducible with
