Hi everyone,
I've been trying to debug my program using MDB. But only a set of mdb's
supported dcmds work for me..
For example, ::kmem_verify returns
mdb: invalid command '::kmem_verify': unknown dcmd name
while vmem, vmem_seg and whatis are recognized.
> ::vmem

fffffd7fff3664e0 is fffffd7fff3664e0+0 (vmem_seg fffffd7fff36cea0) from
vmem_vmem vmem arena
In addition,
::finleaks returns results, but the vmem_seg returned is unknown:

Could anyone please help me?
Why aren't all the dcmds working, and why do some of them return unrecognized
addresses?
What am I doing wrong?:(
Thanks in advance,
Maria
