I have a multijob which has 6 child job. During test, I found that the multijob always show failed even all sub jobs succeed. The error message is:

Finished Build : 1.0.0.1 of Job : Sub_Job_6 with status : SUCCESS

I found the root cause. One of my sub job is to power off, power on the build machine( a reboot actually). After reboot, Jenkins client will re-connect to Jenkins server. The server may think it's a new conversation, the old one has stopped with some exception. So the final result will show failed.
After I removed this sub job, the multijob showed success finally.
