The replication task now starts successfully, however approximately 20 seconds after the replication task starts, TrueNAS kernel panics and reboots. This is a pull replication task from a Debian Buster+ZFS-on-Linux 0.8.4 system with a mix of encrypted (native ZFS) and unencrypted datasets. Based on the kernel stacktrace, this seems to be related to encryption.
I am currently waiting for a video recording of the console with the stacktrace to upload, once that is complete I will link it here somehow. If these kernel stacktraces are written to a file anywhere, then let me know where on the system I can find it, and I will grab the text copy.
