Any ideas as to why these errors are happening? This is causing a bad memory leak.

wp-content/plugins/post-plugin-library/common_functions.php on line 370 

The above line indicates that this is problem with the plugin ​here.

Looking at line 370 my guess is that that plugin is trying to concatenate too many post IDs, exhausting your memory. You should ask the plugin author to fix the code; I would suggest using subqueries.

I'm closing the ticket as invalid because it's a plugin issue, not a core WP issue.

Just more on what filesosofo said, Basically, The plugin is using more memory than is currently allocated to WordPress.

You can increase the memory WordPress allocates for itself byu adding define('WP_MEMORY_LIMIT', '64M'); to your wp-config.php file. The plugin should really do things more efficiently perhaps, but if you use muliple plugins which use a lot of memory, sometimes you need to increase that limit.

Increasing the limit does not work all webhosts, some lock you to a certain limit.
