Failed to spawn jailed process: {e}

Error message

Failed to spawn jailed process: {e}

What it means

execute_local_jail failed to spawn the jailed helper process — the OS rejected the spawn itself (helper binary missing, exec permission, resource limits). Stdout/stderr file redirection was set up but the process never ran.

Solutions

1. Verify the jail helper binary ships with the install and is executable
2. Check {e} for the OS errno (ENOENT, EACCES, resource limits)
3. Fall back to unsandboxed execution if the policy tier allows
