I've been having an issue lately when trying to save products in Magento, we run into a max execution time error. The error gives one of two lines that it errors out on, either:
$ids = $ids + $this->_getTagIds($tag);
return explode("\n", $ids); - which is within the function _getTagIds
within the file /lib/Mage/Cache/Backend/File.php
Does anyone know where to begin troubleshooting this? This didn't happen before about a week ago. I've been bumping up the max_execution_time to see what the limit is but haven't reached it yet and putting an excessive max_execution_time on the server isn't a great solution. Additionaly, this product that I'm trying to save has no tags associated with it, so there shouldn't be an overload getting tag IDs for the product.
