I was working on a extension for our Magento website, but i found out that my cronjob is not working correctly.

Config: appcodelocalQuestcontrolCustomExstentionetcconfig.xml

<?xml version="1.0"?>
<config>
 <modules>
 <Questcontrol_CustomExstention>
 <version>0.1.0</version>
 </Questcontrol_CustomExstention>
 </modules>
 <global>
 <models>
 <CustomExstention>
 <class>Questcontrol_CustomExstention_Model</class>
 </CustomExstention> 
 </models>
 </global>
 <crontab>
 <jobs>
 <CustomExstention>
 <schedule>
 <cron_expr>* * * * *</cron_expr>
 </schedule>
 <run>
 <model>CustomExstention/Observer::test</model>
 </run>
 </CustomExstention>
 </jobs>
 </crontab>
 <frontend>
 <routers>
 <CustomExstention>
 <use>standard</use>
 <args>
 <module>Questcontrol_CustomExstention</module>
 <frontName>CustomExstention</frontName>
 </args>
 </CustomExstention>
 </routers>
 </frontend>
</config>

Object: appcodelocalQuestcontrolCustomExstentionModelObserver.php

<?php
class Questcontrol_CustomExstention_Model_Observer 

 public function test()
 Mage::log("TEST success");
 

?>

What am i doing wrong at this point?

Thanks in advanced!

First of all, check your system crontab for magento cron. I think that magento cron.sh or cron.php runs every five minutes (cron expr: */5 * * * *), but not every minute (your cronjob expr), thats why you can't run your code propely.

Second problem can be logic of magento cron (cron.sh or cron.php) - when it runs, it checks cron_scheduler table and works with it, after that it add new events (and remove old, etc) from that table. May be your cronjob just runs later because of this logic.

And the third problem can be magento cron hangs on. In some cases (eg: your magento store has lots of cronjobs or cronjobs do lots of work, etc.) when your magento require a lot of time to work with cronjobs, cron.sh process can just hangs on and you need restart it.

pS: In one of our projects we added additional system for magento cron control and moved heaviest and longest operations to the system cron, instead of magento cron
