Question

Answer 1

This error was plaguing one of our clients also with very high loads.. changing the admin url value in local.xml fixed both problems

Answer 2

Probably your admin frontname doesnt match with roouter->adminhtml->frontname in app/etc/local.xml

Go to this directory app/etc/local.xml from your magento project and be sure it must be same with your admin panel url-frontname;

<admin>
    <routers>
        <adminhtml>
            <args>
                <frontName><![CDATA[myadminfrontname]]></frontName>
            </args>
        </adminhtml>
    </routers>
</admin>

Your url must be like this

http://www.myproject.com/myadminfrontname/

also you can remove your cache directory with this code.

go to your project root directory and write

rm -rfv var/*

Finally I get over the issue, it was due to sortorder in etc frontend di.xml <item name="sortOrder" xsi:type="string">20</item> .I changed 20 to 60 and the error disappeared.

Answer 4

We've been having the same issue, and dug a little deeper to discover that the issue doesn't directly relate to which routers are loaded but which modules are loaded.

To work this out we added the following debug code:

    app/code/core/Mage/Core/Controller/Varien/Front.php : Line 183

    if ($i>100) {
        file_put_contents('/tmp/debug.txt', Mage::getConfig()->getNode()->asNiceXml());
        Mage::throwException('Front controller reached 100 router match iterations');
    }

When we check the output of this, we can see that ONLY the Mage_Core module is loaded (check the node 'config/modules'. We think there is some kind of race condition that is occuring that means the system is left with a partially formed config that is then cached.

Would be interested in hearing if you have the same situation.
