NoMethodError: undefined method `describe_snapshots' for #<Fog::AWS::RDS::Real:0xc1bbb9e>

[Steve Frank]

I'm having a very odd intermittent issue:

NoMethodError: undefined method `describe_snapshots' for
#<Fog::AWS::RDS::Real:0xc1bbb9e>

notable lines from backtrace:
[GEM_ROOT]/gems/fog-1.14.0/lib/fog/aws/models/compute/snapshots.rb:26:in
`all'
[GEM_ROOT]/gems/fog-1.14.0/lib/fog/core/collection.rb:141:in `lazy_load'
[GEM_ROOT]/gems/fog-1.14.0/lib/fog/core/collection.rb:22:in `each'
[GEM_ROOT]/bundler/gems/cht_aws-a57b46c52309/lib/cht_aws/rds/snapshots.rb:5:in
`rds_snapshots'

options = {
:region => region['regionName'],
:aws_access_key_id => aws_access_key_id,
:aws_secret_access_key => secret_access_key
}

rds_api = Fog::AWS::RDS.new(options)

*rds_api.snapshots.each do |snap|*

This also happens for describe_instances for RDS.

It only happens for RDS. I am performing similar queries for many other aws
services. Only RDS does this every now and then. And when it does, it
happens for all our accounts.

Thoughts on a good way to debug this? I do suspect it is our code, but we
aren't using any global/static vars, so I just can't see how the rds_api
object is turning into a Fog:Compute instance.

Thanks!

Is your app multithreaded by the time that fog is required? If so, and if fog is being required from >1 thread at the time then you may well be running into race conditions associated with `require` in ruby
