[Crash-utility] Issues with ps -a/vtop

[Steven Soulen]

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
