From cedea84e9a59c3996f3176ae8fbdb78c6e131a5c Mon Sep 17 00:00:00 2001 From: trtllm-agent <296075020+trtllm-agent@users.noreply.github.com> Date: Tue, 21 Jul 2026 10:26:33 -0700 Subject: [PATCH] [nvbugs/6484986][fix] Make UCX recvConnect interruptible for shutdown The UCX transceiver's response thread was permanently stuck in recvConnect() waiting for a peer that never connects when a context-only request times out with no gen peer available. CacheSender::Impl::terminate() then blocked on mResponseFuture.get() which hung LLM.__del__/Proxy.shutdown() on pytest teardown. Poll on ucxx::Request::isCompleted() and consult DataContext.getTransferTerminate() so the caller (sender's response thread on shutdown) can cancel the pending recv and exit the loop cleanly. dataTransceiver.cpp already handles a nullptr return. Also remove the corresponding SKIP waiver.
