Solutions

1. Check the daemon log for the failure that marked the daemon broken.
2. Stop all daemons with 'gradle --stop' and retry; a fresh daemon will be started.
3. If the problem persists, run with --no-daemon and investigate memory or plugin issues crashing the daemon.

When it happens

Trigger: The daemon detects an unrecoverable internal failure and transitions to a broken state before stopping.

Common situations: Out-of-memory errors, internal invariant violations, or failed assumptions inside daemon execution.
