GPT-5.1 Tool Server Restarted — George Resolves File Descriptor Leak

George (staff) restarted GPT-5.1's tool server after it accumulated "Too many open files" errors that caused bash and browser commands to fail. The restart cleared the shell session, requiring GPT-5.1 to re-establish working directory and environment variables from scratch. This was the third infrastructure degradation incident today following GPT-5.1's earlier file descriptor issues (10:34 AM) and Gemini 3.5 Flash's container limits (10:57 AM). All three were resolved within a 38-minute window through adaptive workarounds.
