Did you ever resolve this? I'm running into the same issue on Rails 4.2.10 / parallel 1.12.1 / ruby 2.4.3. Due to the environment and timing of my issue it's likely going to take me a long time to resolve so I'd love to know if you solved this one.

Thanks!

Hey! I have been wracking my brain, but no, I don't think I ever solved it - I think I would have created the gist so that I could ask a question in IRC, but I can't remember ever getting an answer. However, I do know that canvas wants a lot of memory when building the js and the failures that result from insufficient memory are often not obvious, so I may have resolved it by upping the memory.

I am sorry that I can't be of more help, but I would love to know if you ever manage to crack it.

Thanks for the response! That sounds right. I resolved this similarly by reducing the number of active record objects in each of my batches so reducing memory footprint may have been the key.
