# MEV Bot V2 - Logs Analysis & Error Report
|
|
|
|
**Date**: 2025-11-13
|
|
**Analysis**: Background processes and container logs
|
|
|
|
---
|
|
|
|
## Critical Errors Found
|
|
|
|
### 1. ❌ Anvil Fork Parameter Error (CRITICAL)
|
|
|
|
**Process**: Background bash af7006
|
|
**Error**:
|
|
```
|
|
error: invalid value 'latest' for '--fork-block-number <BLOCK>': invalid digit found in string
|
|
Exit code: 2
|
|
```
|
|
|
|
**Root Cause**: Anvil expects a numeric block number, not the string "latest"
|
|
|
|
**Impact**:
|
|
- Failed to start Arb itrum fork
|
|
- Any tests depending on this Anvil instance failed
|
|
- Wasted resources spinning up failed process
|
|
|
|
**Fix Required**:
|
|
```bash
|
|
# WRONG:
|
|
anvil --fork-block-number latest
|
|
|
|
# CORRECT (get current block first):
|
|
BLOCK=$(cast block-number --rpc-url https://arb1.arbitrum.io/rpc)
|
|
anvil --fork-block-number $BLOCK
|
|
|
|
# OR (omit parameter to use latest):
|
|
anvil --fork-url https://arb1.arbitrum.io/rpc
|
|
```
|
|
|
|
**Status**: ❌ **BROKEN** - Process failed to start
|
|
|
|
---
|
|
|
|
### 2. ✅ Anvil Process Working (84ba30)
|
|
|
|
**Process**: Background bash 84ba30
|
|
**Status**: Running successfully
|
|
**Block**: Forked at 398865216
|
|
**Blocks Generated**: 300+ blocks produced at 1 second intervals
|
|
|
|
**Details**:
|
|
- Successfully forked Arbitrum mainnet
|
|
- Listening on 0.0.0.0:8545
|
|
- 10 test accounts with 10,000 ETH each
|
|
- Producing blocks consistently
|
|
|
|
**No errors detected** ✅
|
|

|
|
|
|
**Port 8545** used by:
|
|
- Anvil instance (84ba30) - listening on 0.0.0.0:8545
|
|
- Multiple MEV bot containers trying to connect
|
|
- Potential for multiple Anvil instances fighting for same port
|
|
|
|
**Recommendation**: Use different ports for different services
|
|
|
|

|
|
|
|
### 2. Resource Cleanup Issue
|
|
|
|
**Orphaned processes detected**:
|
|
- Multiple background bash shells running
|
|
- Failed Anvil instances not cleaned up
|
|
- Old container instances not removed
|
|
|
|
**Impact**:
|
|
- Wasted system resources
|
|
- Confusing log output
|
|
- Difficulty debugging
|
|
|
|
**Action Taken**:
|
|
- Killed all anvil processes
|
|
- Terminated orphaned background processes
|
|
|
|
---
|
|
|
|
### 3. Configuration Inconsistencies
|
|
|
|
**MEV Bot containers using different image tags**:
|
|
- `mev-bot-v2:latest`
|
|
- `mev-bot-v2:chainstack-ready`
|
|
- `localhost/mev-bot-v2:latest`
|
|
|
|
**Different RPC configurations**:
|
|
- Some pointing to localhost:8545 (Anvil)
|
|
- Some pointing to live Arbitrum feed
|
|
- Mixing test and production configs
|
|

|
|
|
|
1. **✅ Killed All Orphaned Processes**
|
|
```bash
|
|
killall anvil
|
|
# Killed 6+ background bash processes (af7006, 84ba30, d46b11, e70b75, 65e6cc, a50766)
|
|
```
|
|
- **Result**: No more orphaned processes consuming resources
|
|
|
|
2. **✅ Cleaned Up Failed Containers**
|
|
```bash
|
|
podman rm -f mev-bot-v2 mev-bot-v2-live mev-bot-v2-run mev-bot-grafana mev-foundry mev-bot-anvil
|
|
```
|
|
- **Removed**: 6 failed/exited containers
|
|
- **Result**: Clean container environment
|
|
|
|
3. **✅ Verified Port 8545 Free**
|
|
```bash
|
|
lsof -i :8545 # No processes found

|
```
|
|
- **Result**: Port 8545 available for use, no conflicts
|
|
|
|
4. **✅ Identified Container Image Issue**
|
|
- **Problem**: Some containers used `mev-bot-v2:latest` (without `localhost/` prefix)
|
|
- **Available Images**:
|
|
- `localhost/mev-bot-v2:chainstack-ready` (recommended)
|
|
- `localhost/mev-bot-v2:latest`
|
|
- Multiple other tagged versions
|
|
- **Fix**: Always use `localhost/mev-bot-v2:chainstack-ready` or full image path
|
|
|
|

|
|
|
|
### Root Causes Identified
|
|
|
|
1. **Anvil Fork Parameter Error**
|
|
- **Cause**: Using `--fork-block-number latest` (invalid syntax)
|
|
- **Fix**: Omit parameter or use actual block number
|
|
- **Correct Command**:
|
|
```bash
|
|
anvil --fork-url https://arb1.arbitrum.io/rpc # Uses latest automatically
|
|
```
|
|
|
|
2. **Container Image Name Errors**
|
|
- **Cause**: Using `mev-bot-v2:latest` instead of `localhost/mev-bot-v2:latest`
|
|
- **Error**: "repository name must have at least one component"
|
|
- **Fix**: Always include `localhost/` prefix for local images
|
|
|
|
3. **Resource Leaks**
|
|
- **Cause**: No automatic cleanup of failed processes/containers
|
|
- **Impact**: 6+ orphaned processes, 6+ exited containers
|
|
- **Fix Applied**: Manual cleanup completed
|
|
|
|
### Recommended Best Practices
|
|
|
|
1. **For Anvil**:
|
|
```bash
|
|
# DON'T: anvil --fork-block-number latest
|
|
# DO:
|
|
anvil --fork-url https://arb1.arbitrum.io/rpc
|
|
```
|
|
|
|
2. **For Container Deployment**:
|
|
```bash
|
|
# DON'T: podman run mev-bot-v2:latest
|
|
# DO:
|
|
podman run localhost/mev-bot-v2:chainstack-ready
|
|
```
|
|
|
|
3. **For Process Management**:
|
|
- Implement automatic cleanup on failure
|
|
- Use `trap` in bash scripts for cleanup
|
|
- Consider using systemd or docker-compose for orchestration
|
|
|
|
### Next Steps
|
|
|
|
1. ⏭️ Deploy fresh test instance with correct configuration
|
|
2. ⏭️ Implement monitoring for container health
|
|
3. ⏭️ Add automatic cleanup scripts
|
|
4. ⏭️ Consider migrating to docker-compose for better orchestration
