Hey Travis, So it's a bit hard to say from just that what it could be. That stack trace doesn't immediately stand out to me. What would help here is to open up the dump in mdb and git a little bit more information such as the arguments to the functions and the taskq in question. To start off what I might run is something like this: cd /var/crash/volatile In there you should see files with the name of vmdump.%d. So if you have a vmdump.0, you'd run `savecore -fv vmdump.0 .` and then `mdb 0`. If the trailing digit is different, just replace that everywhere. Once you do that you should have a prompt for mdb. To start with run the following: > ::status ... output ... > $C ... output ... > $r ... output ... > $q That last one will cause you to exit.
