Server Error with WP Defender

I am receiving this error which seems to be attached to WP Defender: PHP Warning: stream_select(): You MUST recompile PHP with a larger value of FD_SETSIZE.\nIt is set to 1024, but you have descriptors numbered at least as high as 1156.\n --enable-fd-setsize=2048 is recommended, but you may want to set it\nto equal the maximum number of open files supported by your system,\nin order to avoid seeing this error again at a later date. in /nas/content/live/tactically/wp-content/plugins/wp-defender/app/module/audit-log-module/component/class-wd-audit-api.php on line 108, referer: https://tactically2.com/wp-admin/plugins.php

I am using WPEngine as my hosting provider and they are saying that this is a pluign issue not a server issue. What do I need to do to fix this?

Thanks
