⚠️ Known Issues & Limitations

1. Transaction Count Ratio ⏳

Observation: 50 transactions across 118,433 blocks

Analysis:

  • May be normal for your blockchain
  • Some chains have very low transaction volume
  • Blocks may be mostly empty or contain only mining rewards

Impact: Low - Core functionality unaffected

Action: ⏳ Monitor over 24-48 hours to verify if this is expected

2. RPC Method Warnings ⚠️

Observation: "Method not enabled" errors for:

  • Internal transaction tracing
  • Block reward information

Impact: Low - Optional features unavailable, core functionality works

Analysis:

  • These are non-critical warnings
  • Basic block and transaction indexing works perfectly
  • Only affects optional advanced features

Action: 💡 Low priority - Only enable if internal transaction details needed

Solution (if needed):

  • Configure Besu RPC with: --rpc-ws-api=TRACE,DEBUG
  • Restart RPC node
  • Restart Blockscout indexer

3. POOL_SIZE Configuration 💡

Observation: POOL_SIZE is 10 (was optimized to 15, but reset to 10)

Impact: Minimal - 10 connections are adequate for current load

Action: 💡 Optional - Can increase to 15 if needed for better performance
