The day my social media automation posted exactly zero times in 24 hours was the day I stopped trusting Activity Monitor. RSS said 264MB. Reality was 47GB. Here is how I found the gap and built a launchd job that closes it while I sleep.
Why This Setup Works
The contradiction: "RSS looked healthy, yet everything was dead"
On August 9, 2026, at hour 21 of uptime, something went wrong on my Mac. The automated social media posting agent driven by Claude Code stopped cold. Playwright's launchPersistentContext timed out at 180 seconds, and 24 hours went by with every lane posting nothing.
My first suspicion was memory pressure. I opened Activity Monitor and checked the memory pressure graph. I ran top and sorted by RSS. Nothing looked abnormal. dasd (Duet Activity Scheduler, macOS's background activity scheduler) showed an RSS of 264MB. Heavy, but within the "that's about normal" range.
