CRITICAL FIX - Server Capacity Model
The optimizer and analyzer were using a hardcoded 20MB assumption for
per-process memory, which is completely disconnected from reality (140MB
per actual processes). This caused dangerously high recommendations.
Changes:
1. lib/php-calculator-improved.sh:
- Added get_actual_memory_per_process() function that measures real
memory usage from active FPM pools via ps aux
- Updated calculate_server_capacity() to use actual measured memory
instead of hardcoded 20MB assumption
- Falls back to 140MB default if no active processes detected
2. modules/performance/php-fpm-batch-analyzer.sh:
- Changed memory impact calculation from hardcoded 20MB to using
actual memory_per_process from server capacity calculation
- Now shows realistic memory impact for each domain
3. modules/performance/php-optimizer.sh:
- Extract memory_per_process from server capacity result
- Use actual value in validation check instead of hardcoded 20MB
- Properly cap recommendations to prevent OOM
Impact on 8GB server example:
- OLD: Server capacity 241 max_children (false 20MB assumption)
- NEW: Server capacity ~42 max_children (real 140MB per process)
- Result: Recommendations go from dangerous (105+31) to safe (~5+37)
This fix ensures the entire three-constraint model (memory + traffic +
fair share) uses realistic data, not assumptions.
🧪 Linux Server Toolkit - DEV Branch
STATUS: 🚀 Development & Testing Branch (Separate from Production)
This is the
devbranch for testing, development, and experimentation. Changes here are isolated from production and can be safely tested before merging to main.
🚀 Quick Start
One command - pulls dev branch with YELLOW ⚠️ BETA banner:
curl -sL https://git.mull.lol/cschantz/Linux-Server-Management-Toolkit/archive/dev.tar.gz | tar xz && source linux-server-management-toolkit/run.sh
When exiting (option 0), answer "yes" and cleanup happens automatically - no extra steps.
