Unexpected EOF in archive when Importing VM Template

I faced vm template importing job error.

That job error was "OVMEVT_00C014D_001 Async command failed".

In that job details, I found that stderr of gzip/gtar. It's below.

> stderr:

> gzip: stdin: invalid compressed data--format violated

> gtar: Unexpected EOF in archive gtar: Unexpected EOF in archive

> gtar: Error is not recoverable: exiting now ,

I checked the tgz file whether if it's broken.

Check-sum was correct and Uncompressing manually was succeeded.

So I think VM Template file (tgz) is correct ( not broken )

Next,

I checked Hardware (Oracle VM Server ) trouble.

I tested the hardware but test is finished with no error.
