Errors during cron

I noticed errors in my syslog during cron runs:

Including the node.module file fixes this issue

function taxonomy_access_shutdown() {
  // Update any affected nodes.
   <strong>module_load_include('inc', 'node', 'node.module');</strong>
   $affected_nodes = taxonomy_access_affected_nodes();
</>

These are the error messages:
