PHP 5.1 does not have XMLWriter::writeRaw()

I am getting exactly the same. And now every cron run fails with "exceeded the time limit and was aborted"

Could I have both of you go to admin/reports/status/php on your site and report back the following values:
memory_limit
max_execution_time

Also if you can lookup your server's timeout as well (for Apache servers it's usually in httpd.conf)

PHP memory limit 64M
max_execution_time 30 (although cron aborts within less than a second)

from httpd.conf:
Timeout 120

Also, I added the cron debugging line into my modules.inc to log every cron hit. Here is the result (obviously newest events at the top)

cron 5:10pm Cron run exceeded the time limit and was aborted. Anonymous
cron 5:10pm hit xmlsitemap cron Anonymous
cron 5:10pm hit xmlsitemap_taxonomy cron Anonymous
cron 5:10pm hit xmlsitemap_node cron Anonymous

I made a clone of the site and gradually removed things to see what was causing the problem.
I deleted every node and removed every non-core module except xmlsitemap and the problem was still there!
The server is a standard CentOS 5.4 running php 5.16
(I am using the current Acquia distribution).

I performed a SHOW PROCESSLIST. It only has one entry which is the process of the SHOW PROCESSLIST request itself.

Same for me

Steps to reproduce:
-create new drupal 6.16 installation
-add xmlsitemap 6.x-2.x-dev (today's version)
-enable just the xmlsitemap
-try and rebuild links and it will fail

Server is a stock Centos 5.4 (which uses php 5.16)
The apc accelerator is installed

I ran the same steps as above on another server which has the CentOS customized so that php 5.26 is installed
No error!

Can you try disabling APC on the PHP 5.16 server? Can you check the server's error logs?

Looked at the httpd error_log
Now we are getting somewhere!

PHP Fatal error: Call to undefined function memory_get_peak_usage() in /opt/dr6/jazz/trunk/modules/xmlsitemap/xmlsitemap.generate.inc on line 140

Ah indeed. I can fix that. :)

Same error. Subscribing.

Committed a fix to CVS. Feel free to retest from CVS or whenever the dev build is repackaged.

The problem has re-appeared with a different error in the apache log:

PHP Fatal error: Call to undefined method XMLSitemapWriter::writeRaw() in /modules/xmlsitemap/xmlsitemap.xmlsitemap.inc on line 58

I am using php 5.1.6

After googling around for a solution, I found this code which provides a fallback method for writeRaw when running under php 5.1.6. I added it to end of the class XMLSitemapWriter in xmlsitemap.xmlsitemap.inc and it works perfectly--XML sitemaps will now build.

   /**
     * Fallback method for writeRaw, introduced in PHP 5.2
     *
     * @param string $text
     * @return string
     */
    public function writeRaw($text)
    {
    	if (method_exists($parent, 'writeRaw')) {
    		return $parent->writeRaw($text);
    	}

   	return $this->text($text);
    }

Here is a patch for the above code

Renaming issue to a more accurate and informative title

Same errors since fews days :

Cron run exceeded the time limit and was aborted.
Last cron process did not finish.

But I use PHP 5.2.4.

Tested on several servers and it works for me.

Committed to CVS.
