Zeus startup problems - Postgres

[arizz96]

System details

• uname -a: Darwin MBP.lan 17.0.0 Darwin Kernel Version 17.0.0: Thu Aug 24 21:48:19 PDT 2017; root:xnu-4570.1.46~2/RELEASE_X86_64 x86_64

(macOS High Sierra)

• ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin17]

(I'm using rbenv, but rvm give me the same error)

• zeus
  Tried with:
  0.15.15.pre
  0.15.14
  0.15.13
  0.15.12
  0.15.10 (this gives segmentation fault)

• pg gem
  Tried with:
  0.18.3
  0.21.0

Steps to Reproduce

zeus start on a fresh new project, using PostgreSQL, project gives:
slavenode.go:226: [default_bundle] read unix ->: EOF

On another fresh project, using SQLite, zeus works.

+1 same problem here

Also seeing the same issue. Is there any chance it's related to this issue with forking processes in High Sierra? https://blog.phusion.nl/2017/10/13/why-ruby-app-servers-break-on-macos-high-sierra-and-what-can-be-done-about-it/

It seems to have begun reliably only after I upgraded to High Sierra, and if memory serves me right Zeus uses forking pretty heavily.

I'm still seeing the same problem. Is there any progress on it?

any news about this?

@AndrzejJantos check out this
#617 (comment)

For me, with this ENV, Zeus works

[AndrzejJantos]

Nope, it didn't help.

Zeus is not working on latest mac update + gem 'pg'.

I just want to chime in that export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES fixed my issue on my fresh install of OSX mojave.
