We've seen this issue lately, it could be this:
Here's what Matt Jones said about it:
I believe we've tracked it down to this issue:
https://jira.sakaiproject.org/browse/KNL-797
The problem is that if you're importing or copying one site to another it
has to erase everything from the site and re-add it again, rather than
updating it. If something happens during that processing (it goes slow and
the instructor presses the button again) or there's a network problem, or
something else happens, the site can be damaged. Normally this shouldn't
happen because the method is in a transaction, but so we're not entirely
sure what happens here, and it doesn't seem to happen very often.
