# Block Production Issue - Root Cause Identified
|
|
|
|
**Last Updated:** 2026-01-31
|
|
**Document Version:** 1.0
|
|
**Status:** Active Documentation
|

|
|
|
|
**Date**: 2025-01-20
|
|
**Status**: 🔴 **CRITICAL ISSUE FOUND**
|
|

|
|
|
|
## Critical Problem
|
|
|
|
**Block Production Has Stopped**
|
|
|
|
- **Current Block**: 1145367 (stuck)
|
|
- **Status**: Blocks NOT being produced
|
|
- **Impact**: All transactions cannot be confirmed
|
|
|
|
---
|
|
|
|
## Root Cause Analysis
|
|
|
|
### Issue 1: Nonce Conversion Failure (FIXED)
|
|
- **Problem**: Hex values had quotes (`"0x3330"` instead of `0x3330`)
|
|
- **Solution**: Remove quotes before conversion
|
|
- **Status**: ✅ Fixed
|
|
|
|
### Issue 2: Block Production Stopped (CRITICAL)
|
|
- **Problem**: Network validators stopped producing blocks
|
|
- **Evidence**: Block number stuck at 1145367 for extended period
|
|
- **Impact**: No transactions can be confirmed
|
|
- **Status**: ❌ **REQUIRES IMMEDIATE ACTION**
|
|

|
## Current Transaction Status
|
|
|
|
### Nonce Status (After Fix)
|
|
- **Latest Nonce**: 13104 (confirmed)
|
|
- **Pending Nonce**: 13107 (includes pending)
|
|
- **Pending Transactions**: 3
|
|
- Nonce 13104: Stuck transaction (original pending)
|
|
- Nonce 13105: WETH9 Bridge deployment
|
|
- Nonce 13106: WETH10 Bridge deployment
|
|
|
|
### Deployment Status
|
|
- **WETH9 Bridge**: ❌ Not deployed (transaction pending)
|
|
- **WETH10 Bridge**: ❌ Not deployed (transaction pending)
|
|
- **LINK Token**: ⏳ Not attempted yet

## Solution: Restart Validators
|
|
|
|
### Why Validators Stopped
|
|
Possible reasons:
|
|
1. Validator service crashed
|
|
2. Network connectivity issues
|
|
3. Consensus mechanism stalled
|
|
4. Resource constraints
|
|
|
|
### Fix: Restart All Validators
|
|
```bash
|
|
# Restart all validators
|
|
for vmid in 1000 1001 1002 1003 1004; do
|
|
pct exec $vmid -- systemctl restart besu-validator.service
|
|
done
|
|
|
|
# Wait for initialization
|
|
sleep 15
|
|
|
|
# Verify block production resumes
|
|
BLOCK1=$(cast block-number --rpc-url $RPC)
|
|
sleep 10
|
|
BLOCK2=$(cast block-number --rpc-url $RPC)
|
|
# Should increase
|
|
```
|
|
|
|
---
|
|
|
|
## Verification Steps
|
|
|
|
### Step 1: Check Block Production
|
|
```bash
|
|
# Monitor blocks
|
|
BLOCK1=$(cast block-number --rpc-url $RPC)
|
|
sleep 10
|
|
BLOCK2=$(cast block-number --rpc-url $RPC)
|
|
# Blocks should increase
|
|
```
|
|
|
|
### Step 2: Monitor Transaction Confirmations
|
|
```bash
|
|
# Watch for nonce to increase
|
|
LATEST=$(cast nonce $DEPLOYER --rpc-url $RPC)
|
|
# Should increase as transactions are confirmed
|
|
```
|
|
|
|
### Step 3: Verify Contract Deployments
|
|
```bash
|
|
# Check WETH9 Bridge
|
|
cast code 0x646e0026F8B5BCB94986377a25Da6f89BdCbBF6e --rpc-url $RPC
|
|
# Should return contract code
|
|
```
|
|
|

|
|
|
|
## Expected Outcomes
|
|
|
|
### After Validator Restart
|
|
1. ✅ Blocks resume production
|
|
2. ✅ Pending transactions start confirming
|
|
3. ✅ Nonce increases as transactions are mined
|
|
4. ✅ Contracts deploy successfully
|
|
5. ✅ Bridge destinations can be configured
|
|
|
|
### Timeline
|
|
- Validator restart: ~30 seconds
|
|
- Block production resume: Immediate
|
|
- Transaction confirmations: 1-2 minutes per transaction
|
|
- Full deployment complete: ~5-10 minutes
|
|
|

|
|
|
|
## Troubleshooting
|
|
|
|
### If Blocks Still Don't Produce
|
|
1. Check validator logs for errors
|
|
2. Verify validator services are running
|
|
3. Check network connectivity between validators
|
|
4. Verify consensus configuration
|
|
5. Check for resource constraints (CPU, memory, disk)
|
|
|
|
### If Transactions Still Don't Confirm
|
|
1. Verify block production is working
|
|
2. Check transaction gas prices
|
|
3. Verify transactions are in mempool
|
|
4. Check for nonce conflicts
|
|
5. Verify account has sufficient balance

|
**Status**: Critical issue identified - Block production stopped
|
|
**Action Required**: Restart validators immediately
|
|
