Having recently upgraded from DSpace 5.6 to 7.6.1, we are attempting our first
CLI SAF import into our new production system. When testing SAF imports into
our staging server before going live with production, we had no issues
importing. Now, we’re seeing the following error when importing into both
production and staging systems:

We haven’t found an errors via strace or in the Postgres logs; we’ll turn up
Postgres to debug logging when we keep poking at it tomorrow.
Any thoughts or suggestions as far as what might be going on? What we should
look into more deeply?
Thanks,
-Dave
