Perch filling up /var/tmp and killing the server

Hi,

So I have Perch runway site and as soon as the site has any kind of traffic ( like just 20 people ) the site completely dies.

The server spec is ample:

12 Core

12GB Ram

500GB HDD

The server tech people are telling me that the code and/or database of Perch is filling up the /var/tmp folder on the server to capacity and crashing it.

I really need some help!!

Unsure about the files uploaded but i've screenshot a few of the heavy table in the database (attached) if that helps. I can say that the reseources filder when its zipped up is over 10GB in size so there is a lot of physical files.

The site is filling up the server /tmp folder with .MAD files which then kills the server - screenshot attached

I'm told that they are created when INSERT and/or UPDATE queries are called to the database but sure that shouldn't happen with perch by just people visiting the site??
