Description

The terminal running AI agents suddenly exits without warning during concurrent worktree operations.

Environment

• Setup: Local only
• Scenario: Multiple AI agents working on separate branches concurrently
• Operations: Concurrent git operations, particularly during rebases

Expected Behavior

Terminal should remain stable and provide error messages before any exit.

Actual Behavior

Terminal exits abruptly without warning or error messages, terminating all running AI agents.

Symptoms

• Sudden terminal closure during git operations
• No error messages or logs before exit
• More frequent during rebase operations
• Occurs when multiple agents are active

Potential Causes

• Segmentation fault in git process
• System resource exhaustion (file descriptors, memory)
• Shell crash from corrupted git state
• Signal handling issues during concurrent operations

Impact

• Loss of agent progress and context
• Requires restarting all agents
• Potential for incomplete or corrupted commits
• Disrupts parallel development workflow
