What's Wrong?

Description

When using Claude Code via cc-connect on Windows 10 for extended periods (a full workday with frequent sub-agent and Shell tool invocations), the process count explodes due to unrecycled "Git for Windows" processes.

Observed behavior

• After ~8 hours of use (frequent Agent + Shell tool calls): 21,541 processes, system becomes unresponsive, Task Manager freezes
• After a fresh reboot and ~2 more hours of use: 5,000+ processes, all named "Git for Windows" (git.exe / bash.exe / sh.exe child processes)
• Each Shell/Bash tool invocation appears to spawn new Git for Windows child processes that are never cleaned up
• The leak forces a hard reboot when the system becomes too slow to even open Task Manager

Expected behavior

Shell/Bash tool child processes should be terminated when the command completes. They should not accumulate over the session lifetime.

Steps to reproduce

1. Use Claude Code via cc-connect on Windows 10
2. Run many Shell/Bash commands and Agent tool calls over several hours
3. Open Task Manager → sort by process name → observe hundreds/thousands of "Git for Windows" entries

Environment

• OS: Windows 10 Pro (build 19045)
• Claude Code: cc-connect mode
• Git: Git for Windows (installed at C:\Program Files\Git\)
• Shell environment: Bash (via Git for Windows) + PowerShell 7

Severity

Critical — renders the machine unusable, requires hard reboot. Makes long work sessions impossible.

What Should Happen?

Shell/Bash tool child processes should be terminated and cleaned up after each command completes, rather than accumulating indefinitely over the session.
