nesquena-hermes	2f7c5f01ee	fix(#4973 ): replace per-request diagnostics Timer with a process-global watchdog thread A threading.Timer per RequestDiagnostics spawns one OS thread per request, held alive until finish() cancels it. Under sustained /api/sessions poll load this exhausts the per-process thread cap (RuntimeError: can't start new thread) and the server stops accepting connections. Replace with a single lazy-init watchdog daemon thread that scans pending diags every ~1s; public API unchanged. Caps timeout-tracking at 1 thread/process regardless of request rate.	2026-06-26 07:58:13 +00:00

fix(#4973 ): replace per-request diagnostics Timer with a process-global watchdog thread

A threading.Timer per RequestDiagnostics spawns one OS thread per request, held
alive until finish() cancels it. Under sustained /api/sessions poll load this
exhausts the per-process thread cap (RuntimeError: can't start new thread) and
the server stops accepting connections. Replace with a single lazy-init
watchdog daemon thread that scans pending diags every ~1s; public API
unchanged. Caps timeout-tracking at 1 thread/process regardless of request rate.
