Restarting a node mid-snap-sync can crash-loop during startup chain repair. On a restart mid-sync the pathdb is disabled (`waitSync`), so repair rewinds the stateless head to genesis and asks `StateRecoverable` if it can roll back there. `Recoverable` doesn't check `waitSync`, so it reports genesis as recoverable, but `Recover` does and refuses with `waiting for sync`, tripping a `log.Crit`. The flag is persisted, so the node crash-loops on every restart. CRIT Failed to recover state number=0 hash=37fcdc..6edf0b err="waiting for sync" The fix is to make `Recoverable` return false while a sync is running, so it agrees with `Recover`. Repair then falls through to the existing "wait state sync" path. |
