In-process native code -- pymupdf's classify/metadata `pymupdf.open` and embedded Qdrant -- can segfault the interpreter during indexing. With only PYTHONUNBUFFERED set, such a fault makes the container exit 139 (SIGSEGV) / 133 (SIGTRAP) with no logs at all, which is exactly what #926 reports on a CPU-constrained self-hosted VPS. Enabling PYTHONFAULTHANDLER makes the interpreter dump a Python + C-level traceback to stderr on SIGSEGV/SIGABRT/SIGFPE/SIGBUS, so the faulting library is identifiable from container logs. The handler is dormant during normal operation (no output, negligible overhead). Refs #926 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
