Renderer process crashes (exitCode 5) when connecting to remote server — infinite recursion in constructMessageRows #28984

Description

Description

The desktop app crashes consistently when connecting to a remote server. The renderer process hangs (becomes unresponsive), then exits with exitCode: 5 (killed by OS). This has happened across multiple app sessions today (v1.15.10).

Environment

• OpenCode version: 1.15.10
• Platform: macOS 26.3 (arm64)
• Electron: 41.2.1
• Node: 24.14.1

Steps to Reproduce

1. Open OpenCode Desktop
2. Connect to a remote server (SSH/remote workspace)
3. The app loads the previous session's message history (fetchOlderMessages)
4. Renderer becomes unresponsive → crashes

Expected Behavior

App connects to the remote server and displays message history without crashing.

Actual Behavior

Renderer process hangs, then exits:

[error] (window)  renderer process gone {
  window: 'main',
  currentURL: 'oc://renderer/index.html',
  details: { reason: 'crashed', exitCode: 5 }
}

Root Cause (from logs)

The crash is not a network issue. The window.log captures the renderer unresponsive stack trace, which shows an infinite recursion in SolidJS's reactive system triggered by loading old session messages:

at fetchOlderMessages (session-DrMr1Tk2.js:28817)
  └─ at loadMessages (main-BftoHaU0.js:66068)
       └─ at constructMessageRows (session-DrMr1Tk2.js:20903)
            └─ at createMemo → readSignal → runUpdates → runQueue
                 └─ at cleanNode (styles-CNvLU9FN.js:691)
                      └─ at cleanNode (styles-CNvLU9FN.js:710) ← recursive call
                           └─ at cleanNode ...  (infinite loop)

constructMessageRows creates a SolidJS memo that triggers a reactive update cycle. The cleanNode function calls itself recursively through the dependency graph, locking the renderer thread until the OS kills it.

Full unresponsive sample from window.log:

at Object.constructMessageRows (session-DrMr1Tk2.js:20903:55)
at Object.fn (session-DrMr1Tk2.js:21360:29)
at runComputation (styles-CNvLU9FN.js:486:22)
...
at cleanNode (styles-CNvLU9FN.js:691:5)
at cleanNode (styles-CNvLU9FN.js:710:50)   ← recursive
...
at async fetchOlderMessages (session-DrMr1Tk2.js:28817:7)

Frequency

Reproducible on every connection attempt to the remote server. Occurred in sessions:

• 20260523T133235 — crash
• 20260523T133533 — crash
• 20260523T134641 — crash

Workaround

Starting a new session instead of loading existing remote session history avoids the crash.

Attachments

Debug log bundle exported from the app (Help → Export Debug Logs) is available — contains window.log with full stack traces and 5 crashpad .dmp files.
