PHP out of memory error

I increased the server PHP memory_limit to 512MB (from 128MB). Let’s see if that fixes the issue.

Thanks for the reply.

My WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT settings for WordPress were already at 512MB. I increased the memory_limit in php.ini. We’ll see what happens. It’s possible another plugin I use has a memory leak, as I see memory error messages on triggering on other PHP code lines.

This is still not resolved and I’m pretty sure it is related to UpdraftPlus Backup. The out of memory messages almost systematically point to files in the plugin, like this one:

E_ERROR: Allowed memory size of 536870912 bytes exhausted (tried to allocate 1196032 bytes) (Most recent call first)

wp-content/plugins/updraftplus/vendor/guzzlehttp/psr7/src/Utils.php line 308

Here is the corresponding code in this case:

302     */
303    public static function streamFor($resource = '', array $options = [])
304    {
305        if (is_scalar($resource)) {
306            $stream = self::tryFopen('php://temp', 'r+');
307            if ($resource !== '') {
308                fwrite($stream, $resource);
308                fseek($stream, 0);
309            }
310            return new Stream($stream, $options);
311        }
312
313        switch (gettype($resource)) {

Meaning most likely you have a memory leak because something is not getting closed.

Hmm I’m running PHP 7.4.28 on all the servers seeing the issue, so it seems unlikely this is it, as I would expect this version to have been patched. Must be some other memory leak.
