Hi, I was getting this error page when trying to load traces. I was using version 7.12.2 on a self-hosted setup.

Hitting the memory limit—what were the memory recommendations for Phoenix?

How much memory do you use today? Ours (Also self hosted) is running OK with 1gb of memory. We’ll probably double that in the near future, but we don’t get this error

Can you share the URL you are trying to visit? Just the path is okay if you don't want to share the whole thing

Thanks for the info! Now about the memory limit, are you seeing a warning or error about a memory limit?

So when we load the trace/span/session view we load the contents of the spans into memory before serving them over the API. Typically spans are much smaller and we can paginate but in this case your spans are quite large. For now I think we can do two things:
If you increase the memory limits on your container, it should stop crashing for a while
I have filed an issue so that we can try to reduce memory usage on those pages for the case when spans are extremely large https://github.com/Arize-ai/phoenix/issues/6417

Sorry for the inconvenience! Super interested in hearing about your use case that generates spans with so many tokens 🙂

So these are traces for agent runs with hundreds of documents with text and metadata. I am able to view them fine on langsmith though
