verl [Help] Weird Error Messages in vLLM Async Rollout

Hi,

I am using vllm async rollout feature and I am getting some error messages like this:

(TaskRunner pid=1356207) Exception ignored in: <function _ConnectionBase.__del__ at 0x7fa889565630>
(TaskRunner pid=1356207) Traceback (most recent call last):

(TaskRunner pid=1356207)   File "python/ray/_raylet.pyx", line 837, in ray._raylet.raise_sys_exit_with_custom_error_message
(TaskRunner pid=1356207) SystemExit: 1

This doesn't really block my code and my run seems to work as intended, however, I would like to understand what this is. I suspect that this is coming from how I query a server to get feedback for the second turn but I cannot really pinpoint the issue as the error doesn't really point to where this is coming from. Does anyone have any advice on how to debug this?

Thanks!!
