+- UptimeRobot mailed to say that CGSpace was down
+  - I looked and found the load at 44...
+- There seem to be a lot of locks from the XMLUI:
+
+```console
+$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | grep -o -E '(dspaceWeb|dspaceApi)' | sort | uniq -c | sort -n
+   3173 dspaceWeb
+```
+
+- Looking at the top IPs in nginx's access log one IP in particular stands out:
+
+```console
+    941 66.249.66.222
+   1224 95.108.213.28
+   2074 157.90.209.76
+   3064 66.249.66.221
+  95743 185.192.69.15
+```
+
+- 185.192.69.15 is in the UK
+- I added a block for that IP in nginx and the load went down...
