Hi,

I've been using the new MPO observability tools on several
projects (as a few of you on this list know). They are proving
to be an *extremely* useful addition to the toolkit.

Today I've just hit an issue that I wondered if you'd seen
before. A colleague and I both issued a 'pmap -L' on an
Oracle shadow process at roughly the same time (actually I
forced mine). Unfortunately, not only did both pmap invocations
core but the Oracle shadow process did as well (along with it's
28GB of SGA...).

The stack from pmap looks like:

# pstack core
core 'core' of 1107:    pmap -FL 900
 0000000000404970 get_meminfo () + 70
 0000000000405057 look_lgmap () + 197
 0000000000402267 iter_map () + 47
 00000000004047f1 main () + e91
 0000000000401fbc _start () + 6c


Have you seen this before? I can get you the cores when
the machine is available again. Unfortunately, it's feeling
poorly at the minute though and needs to be massaged to
resume normal service. This is snv_27, ptools-bin-0.1.2 on
an amd based system.


Cheers.

Jon.
