Hi

I am using multiqueue with RSS to read from MT27800 Family [ConnectX-5] 1017

My application receive traffic, and write some data to disk. As a result I/O write is cached in linux memory.
When the server memory is completely cache ( I know it is still available) I start seeing drops at nic.
If I delete the data from disk every minute the cached memory is released to free and and no drops at nic.
How can I avoid the drops at nic?

        total        used        free      shared  buff/cache   available
Mem:           125G         77G        325M         29M         47G         47G
Swap:          8.0G        256K        8.0G
