Hi Yaron
Maybe the caching takes PCI bandwidth?

Subject: mellanox connect x 5 drops when cache full
External email: Use caution opening links or attachments
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?
