(Get the code!)
The reason there is no error message about the failed transfer is because the NC crashed in the middle of the transfer according to both log excerpts above. (The line that starts with `NC is looking for configuration...` is the first one that NC prints when it starts.) Since any incoming request from the CC causes NC to restart, the crashes are easy to miss.
So, this bug is not really about the lack of error messages (we do try to log everything that goes wrong) but about a crash. If this crash still happens with the recent version of the code, I would like to know more about the circumstances so that I can recreate it. I tried a few runs with NC running out of disk space during different stages of instance initialization, with both compressed and non-compressed Walrus downloads, but in all cases the failure to write was handled properly.
