server migration

Hello I am going going thru a server migration and the two files listed were causing my JSitemap instance to crash. Once i increased the memory limit it fixed the issue. However it did not cause an issue on the source server. Would be interested in any feed back....thanks

1. christianlocal/components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/cbpaidsubscriptions.php: @ini_set( 'memory_limit', '48M' );
   christianlocal/components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/cbpaidsubscriptions.sysplug.php: @ini_set( 'memory_limit', '48M' );

CBSubs only increases the memory limit if it's too low with 48M being the absolute minimum. Ensure the memory limit set in php.ini is reasonable (I recommend at least 128M). Do you have an error for your crash? Have you posted your crash to the developers of JSitemap to see if it's an issue with their extension?
