    1. Hi Amar,

      The memory exhaustion error can be seen due to any poorly coded plugin or as you have mentioned about the concept of large files. It depends the website and the coding.

      When you have a bigger site then it is possible that the default memory limit isn’t enough. So, you have to exceed it.
