Christian Weiske has a post to his site with a reminder about a common misconception that can happen because of the wording in a standard PHP message about memory exhaustion.
The indieweb.org wiki has a page about Wordpress with a Criticism section. ?
One of those "issues" listed is Fatal Error memory exhausted [...but] I removed that section because it's nonsense to list a server configuration issue as Criticism.
While the admins reverted the change to put the message back, Christian clarified what meaning of the error message to help clarify the situation. In the case if the example message, the "32 bytes" it mentions is not the amount of total memory it's trying to allocate, it's the amount it last tried and failed at. Christian also points out the role that PHP's own
memory_limit setting has on when this message might pop up.
