What's Happening\n\nAfter upgrading to OpenClaw 2026.3.8, cron jobs set to sessionTarget: "isolated" are timing out. This isn't a general failure for all cron jobs; it is specifically hitting tasks that require tool calls (like file operations or complex agent turns). Manual runs in the main session typically work fine, which points to a breakdown in how the embedded agent handles trusted context in isolated environments.\n\n## The Fix\n\nThere is no direct patch yet. Since this is a regression, start by running the diagnostic tool to check for stale configuration or corrupted plists that might be exacerbating the issue:\n\nnpx clawaid\n\nIf that doesn't clear it, your best workaround is to temporarily set sessionTarget to "main" for your critical cron jobs while the core team investigates the agent-auth handshake. Avoid isolated sessions for tasks that trigger external tool calls until a point release fixes the regression.\n\n## Why This Occurs\n\nVersion 2026.3.8 introduced changes to how the embedded agent processes owner context to maintain gateway access after hardeni. This change effectively broke the communication pipe between the isolated cron environment and the tool-calling executor. The agent hangs while waiting for a response that never arrives, leading to predictable timeouts at your defined limit (e.g., 120s or 300s).\n\n## Prevention\n\nMonitor your task logs for the No reply from agent error string. If you see this in your cron logs, immediately revert your cron configuration to the main session target. Use the clawaid command frequently after major updates to ensure your local environment state matches the updated agent expectations.
