+- Tomcat was killed around 3AM by the kernel's OOM killer according to `dmesg`:
+
+```
+[Fri Feb 15 03:10:42 2019] Out of memory: Kill process 12027 (java) score 670 or sacrifice child
+[Fri Feb 15 03:10:42 2019] Killed process 12027 (java) total-vm:14108048kB, anon-rss:5450284kB, file-rss:0kB, shmem-rss:0kB
+[Fri Feb 15 03:10:43 2019] oom_reaper: reaped process 12027 (java), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB
+```
+
+- The `tomcat7` service shows:
+
+```
+Feb 15 03:10:44 linode19 systemd[1]: tomcat7.service: Main process exited, code=killed, status=9/KILL
+```
+
+- I suspect it was related to the media-filter cron job that runs at 3AM but I don't see anything particular in the log files
+- I want to try to normalize the `text_lang` values to make working with metadata easier
+- We currently have a bunch of weird values that DSpace uses like `NULL`, `en_US`, and `en` and others that have been entered manually by editors:
+
+```
+dspace=# SELECT DISTINCT text_lang, count(*) FROM metadatavalue WHERE resource_type_id=2 GROUP BY text_lang ORDER BY count DESC;
+ text_lang |  count
+-----------+---------
+           | 1069539
+ en_US     |  577110
+           |  334768
+ en        |  133501
+ es        |      12
+ *         |      11
+ es_ES     |       2
+ fr        |       2
+ spa       |       2
+ E.        |       1
+ ethnob    |       1
+```
+
+- The majority are `NULL`, `en_US`, the blank string, and `en`—the rest are not enough to be significant
+- Theoretically this field could help if you wanted to search for Spanish-language fields in the API or something, but even for the English fields there are two different values (and those are from DSpace itself)!
+- I'm going to normalized these to `NULL` at least on DSpace Test for now:
+
+```
+dspace=# UPDATE metadatavalue SET text_lang = NULL WHERE resource_type_id=2 AND text_lang IS NOT NULL;
+UPDATE 1045410
+```
+
+- I started proofing IITA's 2019-01 records that Sisay uploaded this week
+  - There were 259 records in IITA's original spreadsheet, but there are 276 in Sisay's collection
+  - Also, I found that there are at least twenty duplicates in these records that we will need to address
+- ILRI ICT fixed the password for the CGSpace support email account and I tested it on Outlook 365 web and DSpace and it works
+- Re-create my local PostgreSQL container to for new PostgreSQL version and to use podman's volumes:
+
+```
+$ podman pull postgres:9.6-alpine
+$ podman volume create dspacedb_data
+$ podman run --name dspacedb -v dspacedb_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:9.6-alpine
+$ createuser -h localhost -U postgres --pwprompt dspacetest
+$ createdb -h localhost -U postgres -O dspacetest --encoding=UNICODE dspacetest
+$ psql -h localhost -U postgres dspacetest -c 'alter user dspacetest superuser;'
+$ pg_restore -h localhost -U postgres -d dspacetest -O --role=dspacetest -h localhost dspace_2019-02-11.backup
+$ psql -h localhost -U postgres -f ~/src/git/DSpace/dspace/etc/postgres/update-sequences.sql dspacetest
+$ psql -h localhost -U postgres dspacetest -c 'alter user dspacetest nosuperuser;'
+```
+
+- And it's all running without root!
