mod_tile does read system load:
get_load_avg()

If this is higher than config value "ModTileMaxLoadMissing" then 404 is 
returned.

But you should see this in the logfile. Can you enable level info?
ap_log_rerror(APLOG_MARK, APLOG_INFO, 0, r, "Load larger 
max_load_missing (%d). Return HTTP_NOT_FOUND.", scfg->max_load_missing);
