System information

Distribution Name | Debian
Distribution Version | 10.5
Linux Kernel | Linux alpha 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux
Architecture | amd64 (2x Intel Xeon X5690), 288GB ECC DDR3
ZFS Version | 0.7.12-2+deb10u2
SPL Version | 0.7.12-2+deb10u1

Describe the problem you're observing

ZFS appears to crash or hang on commiting TXGs during periods of heavy CPU or IO loads. On this particular machine, there are several virtual machines

Describe how to reproduce the problem

Heavy IO loads on the system will trigger the hang. The most recent incident happened when extracting and moving a 55gb file that was downloaded with nzbGet. I have also seen this happen when receiving large files with rsync over a gigabit connection, and also when a virtual machine on the server is performing a lot of I/O

Include any warning/errors/backtraces from the system logs

Large, so instead of pasting it here I have attached it to the reply.

Yup, I see that now. I'll upgrade to 0.8.4 with backports and see how it runs. Thanks for the quick update!
