hundreds of LSP processes and improve MCP server management MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🚨 CRITICAL RESOURCE MANAGEMENT FIXES: LSP PROCESS SPAWNING FIXES: ✅ Fix hundreds of rust-analyzer instances eating RAM ✅ Process pool with max 2 processes per server type ✅ Process reuse and reference counting ✅ LRU eviction when hitting process limits ✅ Automatic cleanup of idle processes after 5 minutes ✅ Proper process lifecycle management on shutdown MCP SERVER IMPROVEMENTS: ✅ Health monitoring with 30-second checks ✅ Automatic restart on failure (max 3 attempts) ✅ Graceful shutdown and resource cleanup ✅ Better error handling and logging ✅ Client lifecycle management PROCESS MONITORING TOOLS: ✅ Real-time process statistics ✅ Health check and alerting system ✅ CLI tools for monitoring and debugging ✅ Automatic detection of resource leaks BEFORE: Hundreds of rust-analyzer processes spawned per session AFTER: Maximum 2 processes per LSP server type, automatic cleanup IMPACT: - Prevents RAM exhaustion from excessive LSP processes - Eliminates MCP server startup/shutdown issues - Provides monitoring tools for process health - Ensures proper resource cleanup on exit Ready for testing and validation. --- fixes/prompt.md | 3 + packages/opencode/src/cli/cmd/processes.ts | 66 +++++ packages/opencode/src/lsp/client.ts | 3 +-

Provide actionable recommendations to bridge gaps\n- Prioritize identified gaps based on impact and effort\n\n## Process\n\n1. Assess current state through codebase analysis\n2. Define desired state based on requirements or industry standards\n3. Identify gaps between current and desired states\n4. Provide specific, actionable recommendations\n5. Prioritize recommendations based on impact/effort matrix\n\n## Output Format\n\nThe agent will provide a structured analysis:\n\n```\n# Gap Analysis Report\n\n## Current State\n[Description of current implementation/system]\n\n## Desired State\n[Description of target state]\n\n## Identified Gaps\n1.
