WordPress running out of memory but no PHP Fatal error?

    Hi all,

    I just faced an odd issue. I volunteer for a non-profit organization that runs a mid size WP site (as an e-learning platform, with WPML amongst many other plugins).

    When a particular post type was created (calling wp_insert_post), about 60+ hooks would be fired and after one of the wpml hooks was called ( icl_sw_filters_gettext), wp would shut down. I got this information by adding debug statements in WP_Hook.apply_filters. The PHP error log and WP debug log gave no hint about what could be going on.

    Knowing that wpml is a memory hog, I had the idea of incrementing the memory in wp-config.php by calling ini_set(‘memory_limit’, ‘256M’), and this solved the issue.

    With the context above, I’m trying to figure out why is it that WP did shut down for what it looks was a memory issue, while at the same time PHP did not log a Fatal error in the logs. Any hints about what could be the cause of this? Or do you think it might be a red herring?

    Thanks a lot!
