我有一个流水说Upstream，它调用了另一个流水说Downstream。但是Downstream管道在以下控制台日志中停留了10多个小时-
Started by upstream project "Upstream" build number 456
originally caused by:
Started by user XYZ
Running as SYSTEM
Building remotely on <ip-address> in workspace /home/oracle/jenkins/workspace/Downstream
但这不能帮助我理解原因以及如何使其前进。请帮我调试和解决此问题。
