iThemes Security causing excessive memory and I/O usage site

    I’ve spent hours trying to resolve this on one site with this plugin. It’s working fine on another site. On this site, every time I enable the plugin, the memory and I/O shoot up to the maximum (and the site gets shut down eventually). I’ve disabled every other plugin – removed and reinstalled the plugin, spent 5 hours with tech support for my host and nada – it just causes nothing but headaches, even with database backup disabled. (that definitely causes problems – and yes, permissions are ok). Really disappointed as it’s a very useful plugin. Any thoughts?

  • Hi there,

    i have a similar issue – but cant prove if I/O and memory behave the same (i am not the admin). My webspace ran out of free space caused by database backups made almost every minute (even with 50GB space caus backup has ~200MB each).

    my configs for database backup:
    method: email
    backups to retain: 2
    compress: yes
    schedule: yes
    interval: 1 day

    i configured to send only by mail, but all backups were kept for months (in folder /wp-content/uploads/ithemes-security/backups). same behavior also when i changed method to “both” and “only local”. i additionally checked for running wp-cron (Plugin: WP Crontrol) but i wasnt able to find the right cron. and there was no one with that short interval!

    so assume there are 2 issues:
    1. too frequent runs of backup
    2. no delete of old backups (permission on backups folder is: 751)

    i uninstalled the plugin and installed back again, now it seems that its working well.
    (Also i checked other sites, no problem there…)

    best regards,
    martin

    Other options can be that file change scanning is large, but not broken into chunks (turn on “Split file checking into chunks”).

    I’d check to see if .htaccess is updated properly.

    If you don’t have any caching on this site, that might be a good idea, because it will reduce overall resource usage dramatically.

    Try turning on the PHP “opcache” module as well (ask your hosting support if you don’t know how).
