Kernel panic on Snow Leopard #95

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Set up a zpool mirror to a USB drive. (Yes, I know USB is evil.)
2. Run a virtual machine off a non-zfs partition on the USB drive.
3. Make a process in the VM not respond and kill it. (I used a few copies of 
MSWord.)

What is the expected output? What do you see instead?
I expect the kernel to not panic.

What version of the product are you using? On what operating system?
MacZFS 74.1.0
Mac OS X 10.6.7

Please provide any additional information below.
Please see attached output from crash report.

Chances are that the VM partition swamps connections to the USB drive, so that 
it's not able to respond in the timelines that MacZFS wants data from it. As a 
result, it triggers the 'device error' which then triggers the kernel panic.
