# php memory issues

 * I use sqlite cache of two websites. I suddenly have a new message in “site health”
   on both sites that I haven’t seen before. I think this may have occurred with
   the last update of sqlite cache. Here’s the message:
 * ——————-
 * Your PHP opcode cache and its interned strings cache need more RAM allocated 
   to them. Performance
 * 128 megabytes are allocated to PHP’s opcode cache. It is full. [Learn how to configure it.(opens in a new tab)](https://php.net/manual/en/opcache.configuration.php#ini.opcache.memory-consumption)
 * 8 megabytes are allocated to the opcode cache’s strings buffer. It is full. [Learn how to configure it.(opens in a new tab)](https://www.php.net/manual/en/opcache.configuration.php#ini.opcache.interned-strings-buffer)
 * Ask your hosting provider to increase the opcache.memory_consumption directive
   in php.ini, setting it to at least 256.
 * Ask your hosting provider to increase the opcache.interned_strings_buffer directive
   in php.ini, setting it to at least 24.
 * ———————–
 * If I de-activate the sqlite cache the message goes away. If I roll back v1.6.3
   to 1.6.1 the message also goes away. Ideas?

 * Thanks for the question.
 * Yes, I added that health check to SQLite Object Cache. I did it because the WordPress
   code base seems to have outgrown the OPcache defaults. Churning the OPcache slows
   php down a lot, and this plugin’s users have an interest in avoiding that. I’ve
   also logged issues with WordPress and php on this topic.
 * If this health check causes problems for you, please don’t hesitate to let me
   know. I can take it out again, or maybe only invoke it for sites that use the
   APCu RAM cache.

 * OK, that’s fine. I didn’t know that message came right from your plugin. I doubt
   I can have my host change php configurations, I’m on a cheap shared host. Just
   to be clear, I assume that the only impact would be speed, not a data failure?
 * Thanks for all the work and the great support!

 * That’s rightm, it’s purely a performance issue. It’s not a data loss issue.

 * It’s unclear if we’re meant to act on the messaging though (if we can–I’m unsure).
   What do you think? And what’s the worst that can happen if we can’t?
