FATAL: Chef::Exceptions::ChildConvergeError: Chef run process exited unsuccessfully (exit code 1)I took me a few hours to dig in to chef source code to figure out what's really happening. It turned out for me that chef doesn't like ~ (home) that I used in path declarations in the solo.rb file.
As I skimmed through the code, I have a feeling that any errors that occurs during fork process will cause this error message which does not explain anything. If your cause is not the same as me, unfortunately your only option is to go digging through chef source code. :(
