[libvirt-php]

I am using Libvirt-php for a private project, i do however have a problem that seems to occur when i call any function that returns a domain resource. I have gotten 3 different errors so far. First i had a problem with php memory usage going extreme(2gb), then i have had some apache segmentation fault ending up in apache killing the process. I have also had zend_mm_heap corrupted which i think is the most common one. 

I have tried with Ubuntu 10.04, 10.10 and 11.04 repository versions of Apache. Other than that i am using libvirt version 0.9.1 and libvirt-php version 0.4.1. This is within the contexts of Drupal as i am using the code in a Drupal module. 

I have checked out the source code for libvirt-php but since i am no C/C++ developer i have a hard time figuring out what the issue might be. Some help would be greatly appreciated. :) 

Best Regards!
