Support » Plugin: W3 Total Cache » ACP-warning messages in php error log

  • I get a lot of error messages in my php error log when I enable ACP for database & object cache:

    [Tue Apr 2 15:51:05 2013] [apc-warning] Potential cache slam averted for key 'w3tc_key_www.mapsmarker.com_0_object_40b11b25be0b22f6b8878068eec2c40e_0' in /home/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 55.

    Is there a way to fix this?
    Thx

  • I’ve had the same issue for months as well. I’ve had no luck resolving it. How about yourself?

    didnt try again – hope the plugin author takes a look at this…

    It’s not the plug in. From my understanding if has to do with APC (Alternative PHP Cacheing).

    I did read about a fix for it some time ago (something about changing some params in the the apc.ini file), but it didn’t work for me. Anyhow, the errors just fill up my logs and as far as I can tell don’t affect the site all that much.

    Hey I got this to work. You just need to add

    apc.slam_defense = 0
    apc.write_lock = 1

    into your apc.ini and restart apache.

    This worked for me
