描述

Motivation

The workflow e2e_prime is sometimes stuck and reaches timeout, while sometimes finishes normally. See https://github.com/volcengine/verl/actions/workflows/e2e_prime.yml for details.

Plan

  • Reproduce the issue locally with the container and commands used in the workflow.
  • Check where the root cause is.

研究方向
First, examine the workflow file at .github/workflows/e2e prime.yml to understand the commands and environment. Then, attempt to replicate the issue locally using the same container image as in the workflow. Analyze the logs of both failed and successful runs (available at https://github.com/volcengine/verl/actions/workflows/e2e prime.yml) to identify where the process hangs. Look for common causes such as resource exhaustion, network timeouts, or race conditions in test setup.
