Do you see the actual core dump in /cores? If so, could you run pstack on the core file?

This is in global zone
Managed to enable per process coredumps:
[root@kairoshv /var/tmp]# coreadm
global core file pattern: /var/tmp/%d/%f.%p.%n
global core file content: all
init core file pattern: /%Z/cores/core.%f.%p
init core file content: default

Can you try one more thing? mdb -e '::status' /usr/bin/atq core.atq.23387 (if the core file isn't in the current directory, adjust the parameter accordingly).

Or really on any of those core files will probably work.

Using that same core file (core.atq.23387 -- the value may be different in the other core files) can you try mdb -e '8065f02/s' /usr/bin/atq core.atq.23387?

Ok, can you cat the contents of that file and paste them (assuming nothing sensitive -- please verify first of course). My suspicion is that a line starting with a : jobname: has an invalid value.

It should be the third line of the file (and really just pasting the first three lines of the file should be enough)

I've found the issue (the stack trace is slightly misleading). I can supply you a fixed binary, a PI with the fix, or if you're content to wait for the next release (next week), I should be able to get the fix into it.

Jason, many thanks for looking into this and fixing it!
I can wait for regular release cycle if the fix would go in.
In the meantime, I've checked how do OS zones behave and I can see the same problem. Would these need to be updated too?

/usr are a part of the PI image (and get shared by all the zones), aren't a part of a particular instance image, so updating the platform should resolve it for all the zones.

If you're curious the bug (filed upstream since this impacts every illumos-based distribution) is: https://www.illumos.org/issues/13657, and the fix (which should make it's way into illumos-joyent on Monday as it's been integrated upstream) is: illumos/illumos-gate@1d5eda3
