Can you please preload libumem to diagnose the memory leak

# /sbin/dlmgmtd -d 10 &
# mdb -p `pgrep dlmgmtd`

# while [ 1 ]; do dladm show-ether; dladm show-phys; dladm show-link;
dladm show-aggr; sleep 1; done
It iterated 100 times and then I fired up mdb (which had the effect of
making dladm wait):
# mdb -p 13859
Loading modules: [ ld.so.1 libumem.so.1 libavl.so.1 ]

findleaks: no memory leaks detected
Hmm, it does not report any memory leak problem. Do you still see
dlmgmtd uses a lot of memory?
