The buffer/cache skyrocketed after the system started

The device I use is Jetson Orin NX 16G. The buffer/cache skyrocketed after the system started. This is still true after the reboot.
After cleaning with the following script, it will start rising again.

sync
echo 1 > /proc/sys/vm/drop_caches
echo 2 > /proc/sys/vm/drop_caches
echo 3 > /proc/sys/vm/drop_caches

Please help me solve this problem, thank you!

HI,

What is the purpose of this topic? You want to find out why the buff/cache keeps increasing?

This is an abnormal phenomenon, it takes less than half a minute for the buff/cache to reach its limit. I want to know which process is causing this problem. But I don’t know how to check.

let’s us check what is going on.

I would like to know what software and methods can help me identify this issue.

I didn’t see any abnormal increase on my device with free command.

Do you run any specific usecase on your side? Which jetpack version is in use?

Hello, this issue has been resolved. The reason is that the

tracker-miner-f

was using too much bi, and after disabling it, the problem was fixed.
Sorry for the inconvenience.
