message log indicating attempt to disable memory by JSitemap Karma: 0  
Hi All
In the server message log (var/log/messages) I see a lot of the following:

ALERT - script tried to disable memory_limit by setting it to a negative value -1 bytes which is not allowed (attacker 'xx.xxx.xx.xx', file '/xxx/xxxx/public_html/home/components/com_jmap/jmap.php', line 14)

jmap.php reads:
Code:
if($cParams->get('resources_limit_management', 1)) { ini_set('memory_limit', '-1'); ini_set('max_execution_time', 0); ini_set('pcre.backtrack_limit', -1);
Any thoughts?

Hi,

that happens because by default the memory management is done by the component.

If you don't want this you can change the following parameter to 'Server Mode' so to allow the server to decide the memory limit management.

Best regards

What is your opinion on whether the server or the component should control memory?
I am having a general shortage of memory on the vps which I am sorting, but also what is the effect of the attempt to set memory being logged as a spurious attack?

Never faced such setting as an issue, maybe you have some particular log setup on the server.
Normally there is no difference to set the memory limit by a script or by the server settings. If you have not a large sitemap you can leave it as 'server mode' and simply avoid the logging.
