Can't import data: "Too many open files...failed to open stream"

I’m unable to import data (Accounts) in a new instance of SuiteCRM Version 7.6.4 running in a bitnami MAMP stack. :huh:

The following is what greets me when attempting the import…

WARNING: [2] require_once(/Applications/MAMP-New/apps/suitecrm/htdocs/modules/AOD_Index/Lib/Zend/Search/Lucene/Storage/File/Filesystem.php): failed to open stream: Too many open files on line 349 in file /Applications/MAMP-New/apps/suitecrm/htdocs/modules/AOD_Index/Lib/Zend/Search/Lucene/Storage/Directory/Filesystem.php

Can somebody please shed some light onto this critical problem? Thanks

Turn off warnings in your php.ini file or contact you hosting provider to do so. You want warnings and notices turned off in PHP when using SuiteCRM
