[BUG] Memory Leak in Long-Running Process

[DonHugo]

Bug Description

Memory usage grows continuously over days of operation.

Observed Behavior:

• Memory usage increases over time
• No plateau reached
• Eventually causes system slowdown or OOM

Reproduction:

• Run system for 7+ days
• Monitor memory with top/htop
• Observe continuous growth

Expected Behavior:

• Memory usage stabilizes after initial startup
• Garbage collection works properly
• No unbounded growth

Impact: High - Eventually requires restart

Investigation Needed:

• Profile memory usage
• Check for unclosed resources
• Review circular references
• Test with memory profiler (memory_profiler)
• Identify leak source

Acceptance Criteria:

• Memory leak identified
• Leak fixed
• 7-day stability test passes
• Memory usage documented

Testing Command:

# Monitor memory over time
watch -n 60 'ps aux | grep python | grep main_system'
