Component used: WorkManager Version 2.8.0-alpha04

Devices/Android versions reproduced on:

Pixel 2 XL - Android 11
Samsung Galaxy S21 Ultra - Android 12

Please see demo project: https://github.com/emarc-m/work-manager-oom

Steps to Reproduce:

Run the demo app
Tap on QUEUE WORKERS button to enqueue 1_000 one-time unique workers
Monitor the logs for tag TestWM to inspect the progress of the workers running

Comparing when the workers gets executed with WorkManager 2.8.0-alpha04 vs version 2.3.4, version 2.3.4 would execute the workers immediately compared to 2.8.0-alpha04. It sometimes look like the WorkManager using 2.8.0-alpha04 is not executing any of the queued workers.

I also noticed that there's more logging like this in 2.8.0-alpha04:

For comparison, the sample project can also be built using WorkManager 2.3.4.

Expected behavior: The work manager should execute workers similar to 2.3.4.
