8/10 High

When MCP sessions end abnormally, subprocesses continue running, memory climbs, and ports remain bound. No standard lifecycle hook exists in the spec for cleanup. Teams must write custom janitors using cron jobs and watchdog scripts.

Query: “What are the most common pain points with MCP for developers in 2025?”4/7/2026

When an MCP session ends abnormally, the subprocess keeps running. Memory climbs. Port stays bound. No standard lifecycle hook exists in the spec for "clean up after yourself." Teams are writing custom janitors: cron jobs that kill zombie processes, watchdog scripts, restart-on-threshold automation.
