The below script using opcache.enable_cli=1 and opcache.file_cache_only=1 causes the PHP memory usage to continue to increase. If I disable file_cache_only, then the memory usage remains constant. I was able to reproduce in PHP 8.1, 8.2, and 7.4.
To reproduce, set-up scripts test.php and test2.php as listed below, create an empty directory /tmp/opcache, and then run:
php \
-n \
-d "zend_extension=opcache" \
-d "opcache.enable_cli=1" \
-d "opcache.file_cache=/tmp/opcache" \
-d "opcache.file_cache_only=1" \
test.php
When I run the above, the value of memory_get_usage() continues to increase. If I remove the line for "opcache.file_cache_only=1", then memory_get_usage() remains constant.
If it doesn't happen the 1st time, then try running it a 2nd time.
Can you please check why the memory usage continues to grow in this scenario?
Thanks for your help.
test.php:
<?php
for ($i = 0; $i < 10000; $i++)
{
echo number_format(memory_get_usage())."\n";
require('test2.php');
}
test2.php:
<?php
return;
