What's Wrong?

Title: Claude Code memory leak on Linux - conversation context never freed, causes system crash

Environment:

• OS: Fedora Linux 43 (Workstation Edition)
• Kernel: 6.18.12-200.fc43.x86_64
• RAM: 16GB
• Claude Code version: 2.1.52 (Claude Code), Sonnet 4.6
• Platform: Linux x86_64

Description:

Claude Code accumulates memory continuously during a conversation and never releases it. The process eventually consumed 14GB+ of RAM, making the system unresponsive and forcing a hard reboot.

This does not occur on Windows.

What Should Happen?

Like windows or how codex did for fedora

Error Messages/Logs

Steps to Reproduce

1. Start Claude Code on Fedora Linux
2. Begin a conversation involving tool calls (especially bash commands with large output)
3. Run a tool that produces large output - e.g. journalctl
4. Watch memory in system monitor - it climbs and never drops
5. Continuing the conversation accelerates the growth
6. System becomes unresponsive
