A FreeCAD MCP bridge reported clean instance shutdowns as failures 100 percent of the time on Linux, because its liveness check polled immediately after signaling the process group. The agent was sent to retry or kill processes that were already gone.
From the 2026-10-05 pain-radar digest (finding 4): single follow-up issue from the same pseudonymous user, maintainer fixed in v8.2.3. False failure can be as damaging as false success in long agent loops, since it escalates toward destructive retries. Low confidence: one reporter.
