Redis Output Buffer Limit Exceeded in LangGraph CLI

[xochaels]

I'm encountering an issue with Redis when using LangGraph Cloud and could really use some help understanding and resolving it.

I'm seeing the following error message repeatedly in my langgraph_live_log.txt file, specifically on line 2746:
langgraph-redis-1 | 1:M 02 Jul 2025 15:40:15.159 # Client id=98 addr=172.18.0.4:48928 laddr=172.18.0.2:6379 fd=9 name= age=117 idle=2 flags=P db=0 sub=1 psub=1 multi=-1 qbuf=0 qbuf-free=0 argv-mem=0 obl=146 oll=1 omem=41943064 tot-mem=41963568 events=r cmd=psubscribe user=default redir=-1 scheduled to be closed ASAP for overcoming of output buffer limits.

From what I can gather, this error indicates:

• Service: langgraph-redis-1 (which appears to be LangGraph's managed Redis instance)
• Issue: The client connection is being closed "ASAP for overcoming of output buffer limits."
• Memory Usage: The omem (output memory) is 41943064 bytes (approximately 41.9 MB), and tot-mem (total memory) is 41963568 bytes. This suggests the output buffer is indeed growing quite large.
• Connection Type: It's a pub/sub client connection that's hitting these buffer limits.

My main question is: How can I increase the Redis output buffer limits for langgraph-redis-1 within the LangGraph Cloud environment?

Alternatively, are there any other recommended solutions or best practices to prevent this specific "output buffer limits" error with Redis in a LangGraph Cloud setup? I'm open to any suggestions or insights.

Thanks in advance for your help!
