Getting garbled Appium logs when I am trying to programmatically start Appium on and ios simulator and android device in parallel

Do I have the most recent component updates?

• I use the most recent available driver/plugin and server versions

Is the component officially supported by the Appium team?

• I have verified the component repository is present under the Appium organization in GitHub

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I am trying to programmatically start Appium server on 2-4 different devices, different/ same platforms in parallel and it isn't working at the moment with a great success rate. Out of the 5 times I ran it, it fails 4 times.

Here are my Appium logs:

The logs get stuck here ^^ and rest of the execution doesn't start

Please note that my Appium version is 1.22.3 and I cannot upgrade to >2 since there is a java-client limitation.

Expected Behavior

I want the Appium server to start at least for a parallel run with 4 devices.

Minimal Reproducible Example

This is what my testNG.xml looks like:
`

`

This is how I am starting the Appium server. It is failing at server.start();
public synchronized void startAppiumServer() throws Exception { if (Globals.PLATFORM.equalsIgnoreCase("web")) return; /* Check if a server is already running for this device */ if (!servers.containsKey(udidPerThread.get())) { int port = getAvailablePort(); AppiumServiceBuilder appiumServiceBuilder = new AppiumServiceBuilder(); appiumServiceBuilder.usingPort(port); AppiumDriverLocalService server = AppiumDriverLocalService.buildService(appiumServiceBuilder); server.start(); Assert.assertTrue(server.isRunning()); servers.put(udidPerThread.get(), server); System.out.println("Appium Server Started successfully for device " + udidPerThread.get() + " on port " + port); } currentDevice.set(udidPerThread.get()); }

Environment

• Operating system: MAC Ventura 13.1
• Appium server version (output of appium --version): 1.22.3
• Node.js version (output of node --version): v16.13.2
• npm version (output of npm --version): 8.6.0
• Platform and version under test: ios simulator v16.0, android emulator v11, android real device v13

Futher Information

No response

Start at startAppiumServer(), especially server.start(), and review the supplied TestNG suite configured for parallel tests. Reproduce with Appium 1.22.3 on the listed macOS, iOS, and Android environments, then determine whether parallel startup completes reliably for four devices without garbled logs or execution hanging.
