llama-server aborts inside its own static teardown on SIGTERM — the handler calls exit(), stream_session_manager's destructor throws, and the process dies "signal: aborted (core dumped)". mavgpud sends that signal on every eviction, so a routine yield wrote a multi-gigabyte core into systemd-coredump and logged the same line a real crash would. LimitCORE=0 in the unit stops the disk cost. A yielding flag, set by stop and cleared by start, makes the log distinguish the two: only an exit we did not ask for is still reported as an exit. Not filed upstream. Searched ggml-org/llama.cpp for "ggml_uncaught_exception" with SIGTERM and for stream_session_manager and found nothing matching, so the issue still wants writing — by someone with an account on that tracker, which is why it is not in this commit.
