   - Found a bug with the DSpace 6.3 REST API, it returns HTTP 500 for `dc.title` even though it exists in the registry: https://demo.dspace.org/rest/registries/schema/dc/metadata-fields/title
   - Seems to be with any field that does not have a qualifier
   - I filed an issue: https://github.com/DSpace/DSpace/issues/7946
+- I decided to update all the metadata field descriptions in our registry so I can use that instead of the "hint" for each field in the input form
+  - I will include examples as well so that it becomes a better resource
+
+## 2021-09-17
+
+- I filed [an issue about using SPDX License Identifiers in CG Core v2](https://github.com/AgriculturalSemantics/cg-core/issues/41)
+- Peter Ballantyne emailed me to say that CGSpace was very slow
+  - The front page was returning a blank white page
+  - I looked at the database and the connections look low:
+
+```console
+$ psql -c 'SELECT * FROM pg_stat_activity' | wc -l
+63
+```
+
+- Load on the server is under 1.0, and there are only about 1,000 XMLUI sessions, which seems to be normal for this time of day according to Munin
+- But the DSpace log file shows tons of database issues:
+
+```console
+$ grep -c "Timeout waiting for idle object" dspace.log.2021-09-17 
+14779
+```
+
+- The earliest one I see is around midnight (now is 2PM):
+
+```console
+2021-09-17 00:01:49,572 WARN  org.hibernate.engine.jdbc.spi.SqlExceptionHelper @ SQL Error: 0, SQLState: null
+2021-09-17 00:01:49,572 ERROR org.hibernate.engine.jdbc.spi.SqlExceptionHelper @ Cannot get a connection, pool error Timeout waiting for idle object
+```
+
+- But I was definitely logged into the site this morning so there were no issues then...
+- It seems that a few errors are normal, but there's obviously something wrong today:
+
+```console
+$ grep -c "Timeout waiting for idle object" dspace.log.2021-09-*
