  You have enabled concurrency, but git-annex is not able to use ssh connection caching. This may result in multiple ssh processes prompting for passwords at the same time.

  annex.sshcaching is not set to true

NB we had issue with a recent 10GB switch update which was worked around by me reducing MTU on my servers from Jumbo frames to regular 1500 . But it manifested that scp did not work.  Here scp worked (I did scp on typhon from rolando). And for heejung it does not work to `pull` data from roland to discovery.
