我解决了，是pdf布局分析那里导致的，比如pdf有15页，第一个任务是解析1-12页，第二个任务解析12-15页，第二个任务的page_number起始值应该从1或0开始，而不是从12开始。 你可以根据堆栈信息，定位到报错的代码，打印相关的数据。

同样的问题。这个问题解决了吗？

兄弟能分享一下修改后的代码吗

[xdrenn78]

我将paper改成general，可解析。

@KevinHuSh Same problem. Any idea?

Got the same problem several times :(

What's the version? Could you share me with the file? [email protected]

Despite launching the server with docker-compose-gpu.yml, RagFlow remains quite CPU-intensive—likely contributing to this issue. I haven’t fully resolved it, but the following two tweaks helped in my experience:

1. Lower the chunk size.
   Reducing the chunk size noticeably cut down CPU usage and allowed some previously failing chunking jobs to complete successfully.

2. Increase your machine’s virtual memory.
   I ran:

   sudo sysctl -w vm.max_map_count=262144
   

   The value 262144 is recommended by Elastic Search, which RagFlow uses by default.

I have sent the problematic test attachment to your email. Please check your inbox. It was sent from my email address [email protected]. @KevinHuSh

It seems to work well for latest code. Fail to reproduce it.

@KevinHuSh when parse it ,I selected Manual，not General。

[KevinHuSh]

No luck either.
