Description

I have a file system I'm trying to identify the changing data by using a zfs diff. However, it seems to hang indefinitely after starting:

root@mir-dr-zfs01:/root# zfs diff drpool/NBIA-CIPA/cipa@hourly_2014-12-17_11:00-0600 drpool/NBIA-CIPA/cipa@hourly_2014-12-17_12:00-0600

The pool is 120 spindles and mostly idle. The system has 128GB ram. A zfs send incrementing between the above two snapshots is about 7GB and can dump to /dev/null in a few seconds. So resources definitely are not an issue.

I took a few dumps with gcore while the above was running. (attached)

The issue tracker keeps resetting the connection when I attempt to attach the core dumps. I have 3 @ 2.4mb each. Please email me if you want them.
