Remote-dev-server is missing project after restart

[adietish (Andre Dietisheim)]

Hi folks

I am struggling with a running remote-dev-server which is restarting (first shuts down on a Application.exit()) and then is not bound to it’s initial project any more.
One can see this when calling remote-dev-server status $PROJECT. It returns the status as json.
Initially, when remote-dev-server is started, status is sane:

{
  "appPid": 56,
  "appVersion": "IU-243.23654.153",
  "runtimeVersion": "21.0.5b631.30",
  "unattendedMode": true,
  "backendUnresponsive": false,
  "modalDialogIsOpened": true,
  "idePath": "/idea-server",

      "backgroundTasksRunning": false,
      "users": [

      ]
    }
  ]
}

After the restart, the project is missing:

{
  "appPid": 1670,
  "appVersion": "IU-243.23654.153",
  "runtimeVersion": "21.0.5b631.30",
  "unattendedMode": false,
  "backendUnresponsive": false,
  "modalDialogIsOpened": false,
  "idePath": "/idea-server",
  "ideIdentityString": "/home/user/.config/JetBrains/IntelliJIdea2024.3"
}

The problem can’t be reproduced at 100% but it happens quite frequently. Mostly after a period of idle.
I’d higly appreciate any hints that would help me pin point the cause and how to fix this.

ps. I filed this to the eclipse-che issue tracker, where I also have complete logs, if that helps:

Jetbrains Gateway cannot reconnect after client disconnects (idl'ing, network change, etc.)
