Concurrency issues in the first parallel iterations #2574

Open brauliobo opened 2 years ago

brauliobo commented 2 years ago

I'm experiencing a tendency for more errors at the start of a parallel loop using a threadpool (see peach).

For instance, in this project (closed source) everything is required at boot (it isn't using rails autoloader) but sometimes constants aren't recognized as loaded, so I'm seeing several of the errors below which eventually go away.

NameError: uninitialized constant Aws::SQS::Client
Did you mean?  Aws::Client

@brauliobo Do you have steps or some example code to reproduce this error? Thanks.
