Conversation in Eth R&D discord in the Dencun- Interop channel on 9/21:

I'm testing nethermind's blob pool by sending 16k 6-blob txs (16 txs from 1000 senders) and looks like I accidentally killed few nodes https://ethstats.dencun-devnet-8.ethpandaops.io/ 14k txs already sent, 2k left

The spammer being used is here: https://github.com/NethermindEth/nethermind/tree/feature/send-blobs-tool/src/Nethermind/Nethermind.SendBlobs

Besu died with OOM error.

Until we have a good support for Blobs in the txpool, it make sense that we tune some options to reduce the effects of too many blobs
