Hi,

When I start sidekiq from the command line, it runs correctly. When it is
started from monit, I get kgio_ext.so: [BUG] constant not a symbol or
string.

I'm using kgio 2.8.0 and ruby 2.0.0 p353.

I know monit doesn't set some environment variables but I didn't expect to
encounter an issue with Ruby internals if an environment variable is
missing.

Based on the backtrace "kgio-2.8.0/lib/kgio_ext.so(init_kgio_tryopen+0x1a9)
[0x7fe93d120359]" I found the code where the error came from.
http://repo.or.cz/w/kgio.git/blob/8be51237720fd18cb45188f29c717bbac0ca1964:/ext/kgio/tryopen.c#l173

1. Is this an error on kgio?
2. Did I give enough information to pinpoint the issue?
3. How can I debug this? What tools do you use for this kind of problems?

Regards,
Christopher
