@dosubot[bot] commented on GitHub (Mar 2, 2025):

To fix the "can't start new thread" error when using the openrouter model and filling in the API on Dify version 1.0.0 in a cloud environment, you should increase the system resources significantly beyond the documented requirements. Specifically, increase the host memory to 24GB and the system's threads-max limit to a much higher value, such as 752215. This approach has been confirmed to improve performance and resolve the error in similar scenarios [1].

752215

I have modified the value of /proc/sys/kernel/threads-max according to your suggestion, but the problem still occurs.

Updated the value for threads-max to 752215 but still it is not working. I am embedding the data using openAI. My machine is: Ryzen9 with 64 Gb RAM, 16 Core CPU and 4090 GPU with 24GB RAM.

应该是1.0.0bug，这个问题经常出现，0.15没有出现过这个问题，1.0.0这个导致我基本无法正常业务，我已经退回0.15，0.15很稳定，同一个机子没有出现这个问题

@dosubot[bot] commented on GitHub (Mar 10, 2025):

To resolve the "can't start new thread" error in Dify version 1.0.0, especially on high-spec machines, you should update the plugin_daemon image version in your configuration. Change it from langgenius/dify-plugin-daemon:0.0.3-local to langgenius/dify-plugin-daemon:942d694206a1972ae0addd2286a021b62390a8b6-local. This update is the official fix provided by the maintainers and should address the threading issue without needing further system resource modifications [1][2].
