+- CGSpace was unavailable briefly, and I saw this error in the DSpace log file:
+
+```
+2017-07-05 13:05:36,452 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL connection Error -
+org.postgresql.util.PSQLException: FATAL: remaining connection slots are reserved for non-replication superuser connections
+```
+
+- Looking at the `pg_stat_activity` table I saw there were indeed 98 active connections to PostgreSQL, and at this time the limit is 100, so that makes sense
+- Tsega restarted Tomcat and it's working now
+- Abenet said she was generating a report with Atmire's CUA module, so it could be due to that?
+- Looking in the logs I see this random error again that I should report to DSpace:
+
+```

+- Seems to come from `dspace-api/src/main/java/org/dspace/statistics/SolrLogger.java`
