I'm getting an error when I try to import a record into DSpace 3.x:
Exception: FATAL: remaining connection slots are reserved for
non-replication superuser connections

My command is:
./dspace import --test -a -e haydenyo...@wijiti.com -c 123456789/40 -s
/tmp/ -z item_export_2013_Dec_30_1_103.zip -m /tmp/mapfile
The number of max connections is set to 128 in dspace.cfg. This is just
a demo instance of DSpace so there shouldn't be much going on there. I
could increase the number of connections but 128 seems high considering
hardly anyone accesses this instance (I'm the first person to use it in
2 weeks).
Any help much appreciated.
