Mirror Node /accounts endpoint returns 503 for fee collector account (0.0.98)

[quiet-node]

Description

The Mirror Node REST API /api/v1/accounts/{id} endpoint returns 503 Service Unavailable when querying the fee collector account 0.0.98 (EVM address 0x0000000000000000000000000000000000000062) with the default parameters.

Account 0.0.98 is the network fee collector and receives fees from every transaction on the network, resulting in billions of transaction records. When the API attempts to fetch transactions for this account, the database query times out and returns a service unavailable error.

Steps to reproduce

Run the following command:

curl "https://testnet.mirrornode.hedera.com/api/v1/accounts/0x0000000000000000000000000000000000000062?limit=100"

Expected Result:
Account data with transactions

Actual Result:
Request hangs for approximately 20 seconds, then returns:

503 Service Unavailable

Additional context

• Other accounts with normal transaction volumes return successfully
• Adding &transactions=false to the query works around the issue by excluding transaction data
• This affects any client attempting to query system accounts with high transaction volumes
