OpenClaw High CPU and Extreme Control-Plane RPC Latency After Upgrade to v2026.4.29/5.2 (#76562)

After upgrading from v2026.4.24 to v2026.4.29 or v2026.5.2, gateway shows severe performance regression: high CPU, extreme control-plane RPC latency, unstable polling.

Product Idea from this Signal

A CLI tool that runs pre-flight compatibility checks before OpenClaw upgrades and auto-rolls back when the gateway fails to start

405 ▲

OpenClaw ships 13+ releases per month and each one risks breaking gateway startup, scope pairing, channel connections, or plugin loading. Users upgrading from v2026.4.15 to v2026.4.21 hit a scope upgrade pending approval bug that locked them out of the primary interface entirely. Others saw 13-minute silent hangs on first boot, high CPU from RPC latency spikes, and external plugins silently dropped. This tool snapshots the current working state before upgrade, runs compatibility checks against the target version's known issues, and auto-reverts if the gateway fails health checks after upgrade.
