panic: uma_zfree: Freeing to non free bucket index.

BTW, I see in dmesg:

Starting ddb.
ddb: sysctl: debug.ddb.scripting.scripts: Invalid argument
/etc/rc: WARNING: failed to start ddb

What is that about?

Then I see lots of info on the console.

However, on reboot, there's nothing:

from dmesg:
*skip*

No core dumps found.

Where did my textdump go?

Thanks
