Latest Version 2.8.8 – caused physical memory issues

After updating the plugin to the latest version, it didn’t take long for my site to stop working. It used up all of the Physical Memory. Basically kept starting processes and used up all of the resources available. It might be ajax related? Does any of that make sense? I had to have tech support investigate and reset things. This updated plugin, when active, started consuming all the resources. When I deactivated it, things dropped back to manageable. Anyone else seeing this?
