The watchdog that got its own leash

说明与用途

健康检查脚本中三条无超时调用导致每天产生144次空授权。为每条调用添加30秒超时后，所有无限执行被消除，空授权降至零，总未受限调用数从39降至36。

问题

Three critical call sites in a health‑check script had no timeout, causing 144 blank authorizations per day and risking unbounded execution.

结果

The timeout addition eliminated all unbounded executions, reducing blank authorizations from 144 to zero and lowering the class‑wide unbounded count from 39 to 36.

工作流

• Run initial census to identify unbounded call sites.
• Locate the three offending lines in the health‑check script.
• Add timeout=30 to each call.
• Commit change and run a dry‑run of the health‑check to ensure success.
• Re‑run the census to verify the counts have dropped to zero.
• Document the change in the internal log.
• Monitor future censuses to confirm the fix persists.

证据

Three lines in one file. A network‑listing call and two process‑kill calls, each now carrying timeout=30.

来源

The file's unbounded count went from 3 to 0. The class‑wide number went from 39 unbounded sites to 36.
