Complete unresponsiveness

[sniperrifle2004]

I am trying to get ide-haskell-hie 0.7.2 to work, but all information requests appear to be hanging. It does manage to detect capabilities and I can issue requests using atom-ide-ui. The only thing I am getting is uninformative errors from what-the-status., which could be related, but due to the lack of information this is inconclusive:

I have literally no idea what happens with hie, other than that it IS started.

I would like to investigate further, but I have no idea where and how to start.

I am running atom 1.22.1 on archlinux, in a lts-9.17 stack project, with hie 0.1.0.0 (701723324eef5101a0c1bbcfac0d58d6ffaaaef0) from git

Through a combination of core.debugLSP and using a modified version of ide-haskell-ide I figured out that the requests arrive at hie, but no response returns. So the problem lies there.

For others stumbling on this, I was experiencing an instance of this issue: haskell/haskell-ide-engine#400
