Camera disconnection in nvargus-daemon service

It is difficult for us to reproduce this problem, and we cannot turn on the timeout, which will affect the use of the product.
Could it be a software problem? For example, CPU usage/dmabuff usage errors, etc.

What does the following log indicate?

May 6 15:57:40 caper-desktop nvargus-daemon[16064]: (Argus) Error InvalidState: Buffer was already acquired (in src/api/BufferImpl.cpp, function

It’s could be buffer stuck cause. Like buffer consumed take much time.

What causes the buffer to get stuck? Is it still a software problem? I don’t see any error logs in the kernel

Can you check the source code of nvargus-daemon and provide further analysis results?
