Occasionally "Operation not permitted"

I have read the [issue](https://github.com/langgenius/dify-sandbox/issues/97)

But my problem is different, with the same parameters, sometimes my code execution block can be successful, but sometimes it reports an error: `Operation not allowed`

I am also unable to find the relevant execution logs, and I have encountered the same problem while trying to upgrade the version. I have not found a stable reproduce logic, it interrupts the workflow execution every time it appears.

BTW, I'm using a [self-hosted deployment](https://docs.dify.ai/getting-started/install-self-hosted/local-source-code#clone-dify) method, and the version is 0.6.16.

The simplest step for reproduction:
1. Create the example code execution block
2. Rapidly click "Run this step" multiple times (about 10 to 30 times)

Start by reproducing the failure with the example code execution block and repeated “Run this step” clicks, using the self-hosted 0.6.16 setup described in the issue. Investigate the execution path and available logs to determine why repeated runs produce “Operation not permitted”; done means identifying a stable cause and preventing the workflow interruption.
