Donny (강동윤)(@kdy1dev):Today, I hit a serious bug while running long Codex and Claude Code sessions. Every app running under my user account on my Mac died. I still don’t know which session caused it. I checked memory usage and found fseventsd consuming a lot of memory, so I restarted my Mac. Then I told both sessions to continue. Every app died again. For context: the Codex session had been running for about 30 hours and had lots of messages. The Claude Code session was also long-running and managing a large number of subagents. I haven’t yet isolated which one was responsible.
