Sasha CLI failed to archive some workunits

Using Command line interface, I ran this command:

sudo sasha server=. action=archive wuid=W2017*

It prompted that 120 WUs would be archived and I answered Y.

About 23 of the workunits were successfully archived, the remaining 97 failed with a message like this:

{{ARCHIVE: W20170629-141221 assert(memcmp(buf.str()+p+2,wuid,l)==0) failed - file: }}

I tried
{{ sudo ./sasha server=. action=archive wuid=W20170629-141221}}

and got the same failure message.
