 - I definitely need to look into that!
 
+## 2021-04-11
+
+- I am trying to resolve the AReS Elasticsearch index issues that happened last week
+  - I decided to back up the `openrxv-items` index to `openrxv-items-backup` and then delete all the others:
+
+```console
+$ curl -X PUT "localhost:9200/openrxv-items/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
+$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items-backup
+$ curl -X PUT "localhost:9200/openrxv-items/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
+$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp'
+$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
+$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
+```
+
+- Then I updated all Docker containers and rebooted the server (linode20) so that the correct indexes would be created again:
+
+```console
+$ docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | xargs -L1 docker pull
+```
+
+- Then I realized I have to clone the backup index directly to `openrxv-items-final`, and re-create the `openrxv-items` alias:
+
+```console
+$ curl -XDELETE 'http://localhost:9200/openrxv-items-final'
+$ curl -X PUT "localhost:9200/openrxv-items-backup/_settings" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
+$ curl -s -X POST http://localhost:9200/openrxv-items-backup/_clone/openrxv-items-final
+$ curl -s -X POST 'http://localhost:9200/_aliases' -H 'Content-Type: application/json' -d'{"actions" : [{"add" : { "index" : "openrxv-items-final", "alias" : "openrxv-items"}}]}'
+```
+
+- Now I see both `openrxv-items-final` and `openrxv-items` have the current number of items:
+
+```console
+$ curl -s 'http://localhost:9200/openrxv-items/_count?q=*&pretty'     
+{
+  "count" : 103373,
+  "_shards" : {
+    "total" : 1,
+    "successful" : 1,
+    "skipped" : 0,
+    "failed" : 0
+  }
+}
+$ curl -s 'http://localhost:9200/openrxv-items-final/_count?q=*&pretty'
+{
+  "count" : 103373,
+  "_shards" : {
+    "total" : 1,
+    "successful" : 1,
+    "skipped" : 0,
+    "failed" : 0
+  }
+}
+```
+
+- Then I started a fresh harvesting in the AReS Explorer admin dashboard
+
+## 2021-04-12
+
+- The harvesting on AReS finished last night, but the indexes got messed up again
+  - I will have to fix them manually next time...
+
+## 2021-04-13
+
+- Looking into the logs on 2021-04-06 on CGSpace and DSpace Test to see if there is anything specific that stands out about the activty on those days that would cause the PostgreSQL issues
+  - Digging into the Munin graphs for the last week I found a few other things happening on that morning:
+
+![/dev/sda disk latency week](/cgspace-notes/2021/04/sda-week.png)
+![JVM classes unloaded week](/cgspace-notes/2021/04/classes_unloaded-week.png)
+![Nginx status week](/cgspace-notes/2021/04/nginx_status-week.png)
+
+- 13,000 requests in the last two months from a user with user agent `SomeRandomText`, for example:
+
+```console
+84.33.2.97 - - [06/Apr/2021:06:25:13 +0200] "GET /bitstream/handle/10568/77776/CROP%20SCIENCE.jpg.jpg HTTP/1.1" 404 10890 "-" "SomeRandomText"
+```
+
+- I purged them:
+
+```console
+$ ./ilri/check-spider-hits.sh -f /tmp/agents.txt -p
+Purging 13159 hits from SomeRandomText in statistics
+
+Total number of bot hits purged: 13159
+```
+
+- I noticed there were 78 items submitted in the hour before CGSpace crashed:
+
+```console
+# grep -a -E '2021-04-06 0(6|7):' /home/cgspace.cgiar.org/log/dspace.log.2021-04-06 | grep -c -a add_item 
+78
+```
+
+- Of those 78, 77 of them were from Udana
+- Compared to other mornings (0 to 9 AM) this month that seems to be pretty high:
+
+```console
+# for num in {01..13}; do grep -a -E "2021-04-$num 0" /home/cgspace.cgiar.org/log/dspace.log.2021-04-$num | grep -c -a
