    Hello,

    I’m getting this strange error. When I installed the plugin everything worked fine for 1.5 day but then suddenly it was giving http 500 error’s and so on. In the debug.log I found this error, which is constantly being repeated:

    [29-Feb-2016 20:30:24 UTC] PHP Fatal error: Uncaught Predis\Response\ServerException: OOM command not allowed when used memory > ‘maxmemory’. in /public_html/wp-content/plugins/redis-cache/includes/predis.php:8515
    Stack trace:
    #0 /public_html/wp-content/plugins/redis-cache/includes/predis.php(8480): Predis\Client->onErrorResponse(Object(Predis\Command\StringSet), Object(Predis\Response\Error))
    #1 /public_html/wp-content/plugins/redis-cache/includes/predis.php(8459): Predis\Client->executeCommand(Object(Predis\Command\StringSet))
    #2 /public_html/wp-content/object-cache.php(709): Predis\Client->__call(‘set’, Array)
    #3 /public_html/wp-content/object-cache.php(197): WP_Object_Cache->set(‘alloptions’, Array, ‘options’, 0)

    the php memorylimit is already on 256M.

    I hope you can help me with this error!

    Your Redis server is running out of RAM, I’d increase it. This guide might be helpful: https://redis.io/topics/admin

    Problem still not resolved i think,

    I’ve increase the php memory to 512MB, my hoster suggested this. But now I’m not getting this php error, but still the http 500’s in the backend, not frond end.

    As I wrote in the post earlier, your Redis server is running out of memory, not your PHP.
