If you do this for all events listed currently in all crontabs, you need event engine. Currently request to recheck crontabs each minute masks the need to build event list. Switching this to 1-second step breaks former success. But we still can do something like if (per_second_requests_count > 0) sleep(1); else sleep_until_next_minute_margin(); as soon as there will be really few systems where @every_second is used. -netch-
