Alexander,
I have hit this issue twice, once with 12.0u3 in early May and last night with 12.0u4. I see that the fix is due in 12.0u5 but I would like to avoid another outage between now and then. Are the attached files for the /boot/modules directory compatible with 12.0u4 and if so do you think it would be a good idea for me to use them?
Thanks,,
The patch is committed upstream. We'll merge it into U5. Thank you for testing.
Hi Alex, my bad, I noticed that I had connected to a standard FreeBSD box instead of the TrueNAS server, that's why the folder was empty.
Anyways, I've replaced the modules on the correct server and ran some tests over the last few days. The results are good, I didn't experience any crashes...
Michele, it is weird. There should be ~600 files in /boot/modules directory, and there should be about 29 lines in kldstat output. And openzfs.ko should already be in both. Are you talking about TrueNAS 12.0-U3 at all?
Hi Alex, thanks. I copied the modules into /boot/modules but there were no files in that folder, it was empty.
kldstat showed this output after a reboot:
Id Refs Address Size Name
1 3 0xffffffff80200000 227ae70 kernel
2 1 0xffffffff82a12000 1a20 fdescfs.ko
... so I did a "kldload openzfs.ko" and then the output changed to:
Id Refs Address Size Name
1 11 0xffffffff80200000 227ae70 kernel
2 1 0xffffffff82a12000 1a20 fdescfs.ko
3 1 0xffffffff82a14000 45831f openzfs.ko
Does this look right? I'll run a test now anyways. Memory was lowered to 4GBs.

I'm using this particular TrueNas 12.0u3 system as a backup system. It regularly crashes whenever I export VMs to a TrueNAS iSCSI volume. The underlying ZFS pool is encrypted. This TrueNAS instance is running inside HyperV.
The stacktrace shows this:
