[260727~29] 조용한 크래시, 기록 누락, 27시간 신호 침묵
사흘 내내 "돈이 잘못 나간" 사고가 아니라 "아무 일도 안 일어난" 사고들을 쫓아다녔습니다 — 월요일 새벽의 조용한 크래시, 독자 제보로 찾은 성과 기록 누락, 그리고 서킷브레이커 상황에서 하루 넘게 이어진 신호 침묵까지 며칠 정신없이 사고 대응만 하다 보니 글 쓸 틈을 못 냈습니다. 27일, 28일, 29일 사흘을 한 번에 정리합니다. 돌이켜보면 이 사흘은 유독 "조용히 실패하는" 종류의 사고들이 몰렸던 기간이었습니다. 주문이 잘못 나간 게 아니라, 그냥 아무것도 안 일어난 채 멈춰있었던 사고들입니다. 월요일 새벽, 알림 없이 멈춘 매매 월요일 장 시작 직후, 캐시가 얼마나 신선한지를 판단하는 두 기준이 서로 어긋나면서 매매 실행 경로가 알림 없이 그대로 멈춰버리는 일이 있었습니다. 다행히 잘못된…
For three consecutive days, a series of quiet crashes and record omissions were encountered, with 27 hours of signal silence during the trading week. On Monday morning, without any notice, a batch of trades halted unexpectedly, as the two standards used to evaluate the freshness of the cash supply clashed. Fortunately, no incorrect orders were sent or funds received.
The issue was promptly identified and resolved. Readers noticed that the performance statistics had remained unchanged for several weeks, indicating a bug in the cash judgment system. After the fix, they revisited the performance figures, confirming their legitimacy. The most challenging incident involved 27 hours of signal silence during a volatile trading session on Tuesday.
The real-time monitoring process halted without alert, leaving the situation unnoticed until the next day. The incident highlighted the importance of robust alert systems. The trading firm implemented changes to separate trade-related alerts from system status notifications, employing heartbeat and stop detection devices to promptly detect similar incidents of silence.
The firm also adjusted its approach to failed attempts, distinguishing between retryable and non-retryable cases. This multi-layered safety approach reflects lessons learned from previous safe trade practices. In the process, the firm inadvertently removed its daily family-sharing report, which they promptly restored. The story of expanding the range of operational processes and monitoring system health will continue in a future article.
Meanwhile, the team focused more on preventing chaos during failures rather than implementing new features.
