Flow control disabled on Mikrotik, now seeing RX Overruns/discarded packets

Recently deployed CRS305 (10Gb) had Flow Control enabled by default (SwOS) which I started seeing TX Pauses here and there so I decided to turn it off and see what happens and now I see some packets being discarded/Rx Overruns during a Veeam backup job. The issue is between a Veeam proxy and repository.

Should I enable flow control back up as it was obviously doing what it was supposed to do or try and dig deeper? I have two hosts (ESXi) being backup to this repo so it could simply be that the host is having a tough time handling it?
