10 years ago @maci0 What version of ZFS are you using? It would also be helpful to see the console logs, they should indicate which threads are blocked and why.

10 years ago @behlendorf im using version 0.6.2
no idea how to get the console log, journald doesnt log anymore when this happens. this whole system just freezes and never recovers
sysrq doesnt really work either

10 years ago @behlendorf I think this should be pretty easy to reproduce anyway.

10 years ago @maci0 OK, we'll look it to it when we get a chance. Although this will probably be after some additional memory management work is completed.

10 years ago @maci0 I am already working on a fix for this. The plan is to have it in 0.6.3.

10 years ago @ryao , awesome :)
for now I have limited the arc cache to prevent my system from freezing randomly. once 0.6.3 is released i will test again

10 years ago I confirm this bug on ubuntu saucy. Here are the steps to repeat it, and following that a syslog trace showing the problem. You can use this to test whether your fix is enough. This PPA contains the current stable 0.6.1 release.
To repeat: 1: Create a zpool with at least two partitions in a mirror, and zvol 1.5 times system memory. mkswap and set the system to use that as it's only swap space. Create another zpool with a mirror and another zvol, put a file system on it and run a script that changes the content all the time.
Create another script that does snapshots on the zvol with the changing files. Fill up system memory so the swap is engaged. Sooner or later you will get this core dump and a hang. There is no recovery.
