## ⚠️ 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
