Heroku - Memory Leak

So I implemented a simple realtime memory logger:

 const numeral = require('numeral')

    setInterval(() => {
        const { rss, heapTotal } = process.memoryUsage()
        strapi.log.info('💾 Node Memory Usage |', 'rss:', numeral(rss).format('0.0 ib'), 'heapTotal:', numeral(heapTotal).format('0.0 ib'))
    }, 5000);

I found out that the memory leak really seems to be related to the image upload since I saw a spike right after I uploaded a couple images. The memory spiked from the average of 130MB to 430MB. Even after the upload has finished the memory usage seems to not go down again which indicates that there might really be a memory leak here.

Could any one look into this and confirm if this seems to be true?
