warden: I've put a fix for the first thing in illumos, at least, and requested a backport to the LTS release(s): omniosorg/illumos-omnios #1633

warden: If you can unpack the December and January dumps it'd be good to at least get a proper stack trace out of each one first

They'll be in "/var/crash/$hostname" presumably

And you can "savecore -vf vmdump.1" etc

And then for each one, I would: mdb -e '::status; $C' vmcore.1 (etc)

jclulow: thank you, here is the output of the last from December: paste.omnios.org/?354970b37cec87b7#…jWvYhipL8Ggruu5A8A5KoyHn7uWXf8pmbeA

and this is from the January's one: paste.omnios.org/?79dfab341a21f93b#…BkMViXFj8n5opkbd1KxKusDChouvE5MSMvQ

they both look like the ones provided in the two bug reports I referenced weeks ago

warden: tah!
