Hello All,

I ran into this problem were ps –a/vtop can’t access user space.  Looking at the change log it appears a fix was put in as 4.0-3.7.  But I’m seeing this issue with 5.1.3

crash> ps -a 23591

PID: 23591 TASK: ffff8103813be7a0 CPU: 5 COMMAND: "python"

ps: cannot access user stack address: 7fff7d89a75f

crash> vtop 7fff7d89a75f

VIRTUAL PHYSICAL

7fff7d89a75f (not accessible)

This is on a RHEL 5.4 with kernel 2.6.18-194.11.3.el5. What information will needed to debug this? Or am I using these commands incorrectly?

Thanks in advance for any help you can give me.

Steven Soulen
