WordPress Plugin leaking memory

I have a website running on WordPress. I am running the website on Amazon EC2 web servers, with t2.micro instance. (1CPU and 1GB RAM).

I have installed a few plugins and one of them is leaking memory and overloading the main memory of the system and also the swap space of the system. I am unable to determine which plugin is leaking the memory.

Is there a way to determine what wordpress plugin is leaking memory? or if anyone is familiar with plugins listed below that have cause the same problem for you?
