zmq.error.ZMQError: Too many open files

[lbsswu]

I have tested serl in semulation for several times, the following errors are always met when executing "bash run_actor.sh". Could anyone help?

Hmmm, does the actor process kill itself? and does this happen consistently? If you kill and restart the actor node (while keeping the learner running), will you still get this error?

thanks for your reply!

I think the actor process kill itself. This happen consistently.

If you kill and restart the actor node (while keeping the learner running), will you still get this error?

I tried several times in the same command window, and didn't notice this. I'll clear all the processes and have a try.

I killed all the processes and rerun the code, the actor still failed with the same error.

Okay, I think this symptom seems to be due to the underlying replay buffer update from the actor node side to the learner node being slow. Thus it constantly make multiple requests yet stuck in that loop. The best way to resolve this is to try uncomment this line:

This experimental_pipeline_port=5547 uses a different communication protocol, which proves to be more robust to bad network.

Let me know again if this works. If so, I will try to migrate the code to use this by default

Thanks! the actor is okay, but there is a new error on the learner side.
