Hi, Baber

I will try to help you. I will need some additional details to get me up to speed.

Please share the version of the ESXi.

What was the size of that file, 50Mb/s for 120 seconds is at least 6GB?

Are you able to reproduce this again? How you determine that the memory of the ESXi was increased.
