How to detect:

Monitor build duration trends and timeout frequency by job. Alert when builds timeout consistently at configured limits. Check correlation with resource usage (CPU throttling, memory swapping, disk I/O wait).

Recommended action:

Configure appropriate timeout values per pipeline stage using timeout() directive. Monitor resource usage during builds to right-size container limits. Set global and per-stage timeouts. Use buildDiscarder to prevent resource exhaustion. Split long builds into parallel stages.
