I’ve done this. Contacted web host too.. they said it’s an issue with the plugins having a memory leak.. can you please sort it out? See below..
“I’ve checked with one of our senior support staff and according to them that it is not normal for a wordpress plugin to eat up the whole 512 mb of your ram. A WordPress plugin only requires 64 to 96mb of memory. Kindly check if there is an updated version your plugin or any memory leak.
