stresstestapp cause perfetto captured only 1mins log instead of 5mins

[wjj1928]

I use below config to capture android13 bootup trace. it's defined as 5mins log which works fine only bootup and keep device idle.

But if I run stresstestapp (android aosp code at external/stresstestapp) with below command:

adb shell /data/local/tmp/stressapptest -s 180 -M 1536 -C 12
[Uploading logs.zip…]()

then perfettto only got 1mins logs from UI, trace attached. I wait perfetto finished then pull trace file.

Since this stress test used almost 1.5GB memory, I wonder if anything important to perfetto has been killed by lowmemorykiller.

aplog attached as well.
