[mdb-discuss] mdb findleaks reports zero stack?

[Peter Shoults]

Hi,

I am troubleshooting a memory leak issue and have captured a gcore from 
a running process with libumem enabled.  It reports something I have 
never seen before, and that I could not find any information about.  
Here is what findleaks -d reports:

 > ::findleaks -d
CACHE             LEAKED           BUFCTL             CALLER
(SNIP)
0000000101208de8     585         000000010123c3a0     0
(SNIP)

umem_alloc_64 leak: 585 buffers, 64 bytes each, 37440 bytes total
            ADDR          BUFADDR        TIMESTAMP           THREAD
                            CACHE          LASTLOG         CONTENTS
       10123c3a0        10123b080    71236ea2aea11                1
                        101208de8                0                0

Can anyone explain why I am not getting any printed caller or stack output?
