is this a physical server with an installed client backup

or is it a VM backup?  (just want to be sure because vm restores don't do well with large File Level Restores)

it is a physical server.

If I run the restore via avtar is starts restoring 10 files at a time (each file is 17.5 gigs).  If I run the restore via avamar gui console on windows, it starts restoring 1 file at a time (each file is 17.5 gigs).

The thing I am restoring.  about 200gigs, 38 files.

Can you post the complete log? You should strip out sensitive information (hostnames, IP addresses, etc.) before posting it.

Without seeing the exact messages, there is no way to determine what went wrong. If you're running a command line restore and want to record the log information to a file, specify the log filename by adding the following flag to the avtar command line call:

--logfile="/path/to/logfile"

There's not much information here about what might be going wrong other than the client not being able to flush restored data to disk which can happen for a number of different reasons. I would recommend re-running this test with the --debug flag added to the command line, opening a service request and attaching the log file to the SR.

Is there any documentation to explain the error?  I have support, and there is nothing wrong with it.  But it would be a pain for me to be allowed use it.

The messages in the log are messages about symptoms, not causes. It's not clear what is causing the problem, only that data stops being written to disk (the internal warning), then the client crashes (fatal signal 11).

Let me repeat myself.  I am looking for documentation on the errors within the log file and the syntax of running avtar so I can solve my own problems. Making a beeline to solving this specific problem is nice but what about the next 50 problems?  The "--help" option on the avtar command is a bit sparse.

After 30 minutes, the site finally let me in. 

Thanks for the response.
