Devices do not run tests due to device busy

[CharlanSofist]

Describe the bug

I have a test battery to run and I have several devices with different configurations in the farm, they all appear in the farm, but when I go to run the slowest ones they take a long time to generate the build in the builds tab and the fastest ones are already running, but when the fastest ones reach the end they wait for the queue to clear so they can run the next test, so they stop, this only happens when I have many devices connected, test with only 2 devices and this does not happen, when I am running with 13 devices this happens.

In this case, the slowest device times out and only after that do the other devices start running the tests. In my code, I run the tests individually so it is parallel for each device. Below is how I am starting the server and the capabilities that I am sending.

appium server -ka 800 --local-timezone --use-plugins=device-farm --plugin-device-farm-platform=both --plugin-device-farm-booted-simulators --plugin-device-farm-max-sessions=32 --allow-insecure adb_shell --plugin-device-farm-live-streaming

capabilities: UiAutomator2Options options = new UiAutomator2Options(); options.setDeviceName(deviceName) .setPlatformVersion(platformVersion) .setPlatformName(platformName) .setUdid(udid) .autoGrantPermissions() .setApp(appPathRelative) .setAutomationName("UiAutomator2"); options.setCapability("logLevel", "debug"); options.setCapability("df:liveVideo", true); options.setCapability("df:recordVideo", true); options.setCapability("df:saveDeviceLogs", true); options.setCapability("df:build", deviceName);

@saikrishna321 How we can clean up sessions present in queue ? Because when I m running multiple scripts in parallel, somehow for some reason session are getting into queue list and after that session null pointer is coming.

@Jitu1888 Currently, we don't have this feature.

when I m running multiple scripts in parallel, somehow for some reason session are getting into queue lis This will happening when all the devices are busy and a request for create a session has reached the plugin.

Hi @saikrishna321, Can this be queued for development?
