PreprocessorService::run | end - {"stack":"Error: PixGenie process failed with exit code 11. STDERR:

What Happened#

2026-07-03 18:21 KST, PixGenie 전처리 Python 프로세스가 capture_727017 작업을 정상 완료한 직후 프로세스 종료 시점에 libfoundation.so::bootstrap::unload() 경로에서 SIGSEGV(11)로 죽었다. 결과 파일(pixgenie_result.json)은 이미 디스크에 기록된 상태였지만, 프로세스가 exit code 11로 반환되면서 Node.js wrapper가 이를 실패로 판단해 capture 상태가 Error로 변경되었다. 지난 14일 동안 이 시그니처는 1건만 관측되었다.

Quick Facts#

Field Value
exception.class Error (Node.js) → SIGSEGV(11) in Python child
exception.message PixGenie process failed with exit code 11
top_frame libfoundation.so : cupix::foundation::factory::detail::unregisterObjectCreator
failing binary /tmp/lib/pixgenie/pixgenie/lib/pixgenieutil-x64-ubuntu22.04-gcc-release/libfoundation.so
child PID 33
capture_id 727017
env production, us-west-2

Affected Teams#

Team / Domain Error Count Impact
cana / pano-postprocessor 1 1개 capture(727017)의 PixGenie 전처리가 실패 상태로 마킹됨. 파이프라인 산출물(pixgenie_result.json)은 실제로 생성되었으나 exit code로 인해 활용되지 못함
