Describe the problem you're observing

Kernel Panic observed when executing decryption and tar in large file example 3GB-20GB Files.
In all occasions txg_sync process was blocker for more than 120 seconds.

Describe how to reproduce the problem

Kernel Panic observed when executing decryption and tar in large file example 3GB-20GB Files.
This state was observed in both state where we limit the size of the ARC.

But luckily or unluckily we didn't observe this error when limiting ARC max to 2GB.

Include any warning/errors/backtraces from the system logs

I don't think we can support Ubuntu distro here my friend. Please go to somewhere to Linux related site.

ZFSguru is based on FreeBSD, so as karmantyu said you may not find much help here for a linux related issue.
