    Hi,

    We are uploading a number of posts on an automated, periodic process. We notify the search and filter plugin to update its cache for each post so they appear in our front end search. However, since adding the cache notification we have encountered this problem. Increasing the available memory did not seem to solve the issue, so presumably something is not releasing memory when it is done using it. Is there any common configuration mistake we may have made when adding the cache notification?

    The automated process does work… for a while, which also leads to the diagnosis of unreleased memory.

    Also, is there any guidance on what an ideal memory usage amount might be?

    205520896 bytes is 205MB which is an unusual memory size to allocate. There are two variables that might affect the process.

    The PHP variable memory_limit set on your server. Generally, I would normally recommend this be at least 256MB, but the more the better, up to maybe 1024MB.

    The WordPress WP_MEMORY_LIMIT (set in the wp-config.php file, if not set this will default to 40MB). Note, when setting this, it is set as M not MB. I normally recommend this to be no more than 50% of the PHP memory limit, and at least 128M. I personally prefer to set this at 256M (and thus the PHP memory limit at a least 512MB).

    If memory is not being released, that suggests that something odd is happening, as this is not normal.
