Hi all,
I’ve been running OoO 1.6.1 on my MBP for half a year with great joy and success. I’ve since upgraded to Sierra, and later to a newer MBP, with everything working flawlessly.
A few weeks ago, I upgraded to OoO 1.7.2. Shortly after that, my system started hanging at seemingly random times, forcing me to power off. I’ve logged exactly ten such hangs in the course of two weeks.
To rule out pure coincidence, I reverted to 1.6.1 last week and found my system hasn’t crashed since. I’m perfectly fine sticking to 1.6.1 for now; still, I’d love to sort it out so I can upgrade again.
I’ve been unable to reproduce those hangs exactly, and couldn’t find any hints in my log files either. The only lead I have is that this only seems to happen in situations with some disk activity (e. g. in the middle of rsyncing an unrelated HFS+ volume to another.)
Whenever a hang occurs, it always seems to follow the same script: suddenly, every app beachballs, apparently as soon as it tries to access the disk. The only exception are open Terminal windows where a shell is idling; I can click into those and type commands until I press Enter, then the shell will hang, too. Eventually, there’s nothing left to do but to force power off the system.
My only ZFS dataset (mod parents) is my home mount; the rest of the root filesystem is formatted HFS+. Either partition is a separate encrypted CoreStorage stack; I don’t use ZFS’s encryption.
What are possible ways to narrow down the issue?
Thanks a lot in advance and kind regards!
Claudia
