Hey @Subham7201, Theia is supposed to terminate these processes on its own. It looks like you're running into #15528, but we've failed to reproduce this issue. If you like, you can post more context in there to help us reproduce and fix the issue. |

Hi @msujew, Thanks for your quick response. I’ve verified that WMIC is present on my system. The issue only occurs when the application is packaged through Electron (as an However, in the development environment, the ports are properly released and everything works as expected. |

Adding OnI installed Theia IDE for Windows from theia-ide.org and launched a Spring application from the IDE launch configuration. However, when I closed the IDE, the Java process was still running in the background, and the port remained occupied. Below is the launch configuration for the same: {
"type": "java",
"name": "Launch Application",
"request": "launch",
"mainClass": "dummy.Application",
"cwd": "${workspaceFolder}",
"console": "internalConsole",
"stopOnEntry": false
} |

Unfortunately, I'm pretty busy at the moment and don't really have time to look into this. Issues that only appear in the packaged application are generally rather difficult to debug. However, feel free to give it a try and let us know in case you find out more. |

Hi @msujew, I've spent some time investigating this on my end, but unfortunately I haven't been able to identify the root cause or come up with a fix. The issue consistently occurs in the packaged .exe but works fine in development, which makes it tricky to debug. Thanks again! |

Hello Team,
When I close Theia while running processes (like a Spring Boot app on port 8080), those processes keep running and keep their ports occupied — even for terminal launches, debug sessions, or run configurations.
Here’s my current workaround using
beforeunloadeventListener:Is this the right approach, or does Theia provide any built-in mechanism for process cleanup?
Looking for guidance on the recommended approach for handling process cleanup on IDE closure/reload.
Thanks in advance!
