Walkthrough

Modified the memory watchdog loop in start-server.sh to use a direct used-percentage calculation formula: (total - available) / total, and added LC_ALL=C environment variable to ensure consistent numeric parsing across different locales.

Poem

🐰 A watchdog's memory, once askew,
Now counts with LC_ALL, tried and true!
From total minus free, the tale rings clear—
No locale confusion—just precision here! ✨
