HIE seems to be able to typechek only one module #680

Description
I use HIE with LanguageClient_neovim. Versions:
$ ~/.local/bin/hie --version
Version 0.2.0.0, Git revision e159e35a5471bcfa8576d663cb82180dc9fe53ab (dirty) (1555 commits) x86_64 ghc-8.2.2
$ stack --version
Version 1.7.1, Git revision 681c800873816c022739ca7ed14755e85a579565 (5807 commits) x86_64 hpack-0.28.2
I build HIE with $ stack --resolver=lts-11.2 --stack-yaml=stack-8.2.2.yaml install, since we have LTS-11.2 in the project I develop.
The project consists of a library and an executable in separate Cabal files. The executable is built with -dynamic, so I also have to add -fexternal-interpreter to its Cabal file.
However, it seems that HIE can typecheck only the first file I open in nvim. All subsequent files result in didn't get typechecked module. Here's a part of log with --debug --vomit:

Also, ps indicates that ghc-iserv-dyn process dies after this. How can I debug this further?
