Cron.php Running Twice – Magento Cron.sh Issue

cron

I have a cron job set up to run the cron.sh file every 5 minutes, as per the installation guide. I have checked the server's cron log history and it is correctly running the job on schedule.

I added file_put_contents('cronlog.txt', date('c') . "\n", FILE_APPEND); to the end of the try block in cron.php to verify, but it's logging two identical dates every 5 minutes, like cron.php is calling itself recursively.

Is this normal behaviour? If not, any ideas as to what could cause such strangeness?

On newer versions this is expected. If you take a look at cron.php this part would get executed:

        shell_exec("/bin/sh $baseDir/cron.sh $fileName -mdefault 1 > /dev/null 2>&1 &");
        shell_exec("/bin/sh $baseDir/cron.sh $fileName -malways 1 > /dev/null 2>&1 &");

which then loops through cron.sh to call the cron.php again two times. It gets executed once in always mode and another time as default

    Mage::dispatchEvent($cronMode);

Magento – Parsing error line 39 cron.php while running from command line

<b>Parse error,</b>: syntax error, unexpected T_OBJECT_OPERATOR in <b>/full/path/to/htdocs/cron.php</b> on line <b>39</b><br/>

BTW, here is the cron.php file.

That seems — unlikely. I saved the source of the include cron.php file to a file on my system, and ran the basic PHP lint on it

php -l /path/to/cron.php
No syntax errors detected in /path/to/cron.php

The error you're getting is a Parse Error. This means no PHP executes, because the code syntax is completely wrong.

I'd check

That your version of PHP isn't some ancient PHP 4 version ($ php -v)
That the version of cron.php you're running for the error is the same version of cron.php you're looking at to debug.

Fix Cron Issues – Last Heartbeat Older Than X Minutes in Magento

Try this command:

wget -O /dev/null http://www.domain.com/cron.php

For debug purposes you can set every 3-4 minutes instead of every 10 minutes. If everything is working properly - in your database in table cron_schedule you will see cron tasks. If this table is clean - something went wrong.

upd.1

Don't be afraid, your cron runs like clockwork. In your table you see, that cron started successfully and completed successfully.

You got an error "Last heartbeat older than x minutes". In my opinion its very specific issue and related to some 3rd party extension. Try to search on your host this phrase. For example using SSH:

grep -rni 'Last heartbeat older than'

And upload full text of this method in your post.
