Enabling cache with Memcached or Redis kills the CPU

[pishta74]

Hello Everyone,

 

It's Prestashop 1.6.1.4, I have tried it with php-memcached and Redis Cache, and what happens is, when I enable any of them, php-fpm services fire up and within 1-2 minutes the server CPU is at 100%, rendering. There are no connections from outside at this time.

When I disable caching, it slowly stops.

 

The server is an i7 with 64Gb RAM, apache 2.4.23 and php v7.0.11

 

Any ideas what this could be?

 

All the best,

Istvan

Use apcu and you'll have no problems and better performance.

Ok, I've isntalled pecl-apcu but Prestashop doesn't seem to be supporting it (is there a module for it?)

 

Best,

Istvan

I've installed that via pecl and enabled, when I switched to APC caching it killed the php engine instantly (went dead).

I have also tried to enable plain file system caching and the same thing happens as with memcached or redis, just slower - it starts up php and rendering something with high cpu load.

Is this a known problem? Any reference to it? Is there a way to make memcached or redis work properly with Prestashop 1.6.1?

 

Thanks all!
