|title=<nowiki>Private executable TMPDIR exceeded the Unix socket path limit</nowiki>
|question=<nowiki>How can a GPU runner keep temporary files on an executable private mount without exceeding vLLM ZMQ IPC path limits?</nowiki>
|attempt=<nowiki>The runner assigned TMPDIR to a deeply nested per-model directory under the repository-private executable cache.</nowiki>
|context=<nowiki>Failed B200 migration bundle b200-2-generation-20260717-a02 at source commit fd7f9bdb5817c497996b6c44c233010a743cdb74.</nowiki>
|observation=<nowiki>The lexical project venv and private vLLM snapshot passed. During Qwen engine initialization, ZMQ rejected its generated ipc path because the Unix sockaddr path exceeded 107 bytes. The suite failed before any GPU compute process or generation record.</nowiki>
|interpretation=<nowiki>Filesystem execution safety and IPC lexical path length are separate constraints. A long executable target can be exposed through a short owner-only /tmp symlink alias so socket names stay short while file operations still resolve to the executable private mount.</nowiki>
|reusable_lesson=<nowiki>Budget Unix-domain socket path length using the final generated suffix, not only TMPDIR itself. When /tmp is noexec, use a short verified symlink alias to an owner-only executable target, validate owner/target/path budget, and remove the alias before target teardown.</nowiki>
|applicability=<nowiki>Applies to vLLM, ZeroMQ, multiprocessing, and other Unix-socket runtimes launched from deeply nested workspaces or containers.</nowiki>
|confidence=<nowiki>high</nowiki>
