Website is crushing when plugin is activated

Hi, we already used this plugin for a long time, but now our website gives 508 error code (recourse limit riched). When the plugin is activated our hosting resources reaching limits, all physical memory, I/O usage are loaded for 100%, we have to rename plugin folder to deactivate it, and then our site starts working again. We see the same issue on our second site also. Can you please help us to solve a problem. With regards.
