+- Francesca was having issues with a submission on CGSpace this week
+  - I checked and see a lot of locks in PostgreSQL:
+
+```console
+$ psql -c "SELECT application_name FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid" | sort | uniq -c | sort -n
+      1 
+      1 ------------------
+      1 (3506 rows)
+      1  application_name 
+      9  psql
+     10  
+   3487  dspaceWeb
+```
+
+- As before, I see messages from PostgreSQL about processes waiting for locks since I enabled the `log_lock_waits` setting last month:
+
+```console
+$ grep -E '^2022-01*' /var/log/postgresql/postgresql-10-main.log | grep -c 'still waiting for'
+12
+```
+
+- I set a system alert on DSpace and then restarted the server
