+- Re-sync DSpace Test with CGSpace
+- Help Sisay with OpenRefine
+- Enable HTTPS on DSpace Test using Let's Encrypt:
+
+```
+$ cd ~/src/git
+$ git clone https://github.com/letsencrypt/letsencrypt
+$ cd letsencrypt
+$ sudo service nginx stop
+# add port 443 to firewall rules
+$ ./letsencrypt-auto certonly --standalone -d dspacetest.cgiar.org
+$ sudo service nginx start
+$ ansible-playbook dspace.yml -l linode02 -t nginx,firewall -u aorth --ask-become-pass
+```
+
+- We should install it in /opt/letsencrypt and then script the renewal script, but first we have to wire up some variables and template stuff based on the script here: https://letsencrypt.org/howitworks/
+- I had to export some CIAT items that were being cleaned up on the test server and I noticed their `dc.contributor.author` fields have DSpace 5 authority index UUIDs...
+- To clean those up in OpenRefine I used this GREL expression: `value.replace(/::\w{8}-\w{4}-\w{4}-\w{4}-\w{12}::600/,"")`
+- Getting more and more hangs on DSpace Test, seemingly random but also during CSV import
+- Logs don't always show anything right when it fails, but eventually one of these appears:
+
+```
+org.dspace.discovery.SearchServiceException: Error while processing facet fields: java.lang.OutOfMemoryError: Java heap space
+```
+
+- or
+
+```
+Caused by: java.util.NoSuchElementException: Timeout waiting for idle object
+```
+
+- Right now DSpace Test's Tomcat heap is set to 1536m and we have quite a bit of free RAM:
+
+```
+# free -m
+             total       used       free     shared    buffers     cached
+Mem:          3950       3902         48          9         37       1311
+-/+ buffers/cache:       2552       1397
+Swap:          255         57        198
+```
+
+- So I'll bump up the Tomcat heap to 2048 (CGSpace production server is using 3GB)
