[Deal Making Issue] Retrieval stall after a few GiB of transfer

[kernelogic]

For a few weeks now I cannot perform any retrieval to completion. Tried with different miners and the retrieval would start transfer and just stall after a few GiBs. The latest failure happens on client 1.9.0-rc2 and miner 1.8.0.

On the miner side it shows "peer appears to have hung up" but I didn't "hung up" on anyone but patiently waiting.

I think this may be dealt with in #6185

"peer appears to have hung up" means that the connection to the peer has gone down.

The next release of markets should take care of this issue - when the connection goes down the client will automatically reconnect and restart the data transfer. You can track progress here: #6149

Thanks for your patience :)

Can't wait to try it out. I hope the slingshot judges will use this new version of market to do the judging.
