Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. [gufei.wzy@v101170.sqa.cm4 ~]$ sudo -u admin sh ./jvmtop.sh 22507

What is the expected output? What do you see instead?

I got these exceptions and the process terminated.
