Genserver time out crash in long-running pipeline

[starcraft66]

I wrote a crawler that crawls media galleries to download them and download files uing HTTPoison in a custom pipeline. This seems to work fine for small files as they download quickly but if I try to crawl a really big file like a video, I will almost always get this crash:

12:49:51.241 [error] GenServer #PID<0.471.0> terminating

Is there a setting I can tweak to allow my pipeline to run for much longer? I didn't see anything easily tweakable in the config.

I would suggest firing off a Task instead or moving such heavy data processing to a separate process tree. Pipelines was designed for lightweight data processing.
