 - Create and merge a pull request ([#429](https://github.com/ilri/DSpace/pull/429)) to add eleven new CCAFS Phase II Project Tags to CGSpace
 - Atmire responded to the [Solr cores issue](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=685) last week, but they could not reproduce the issue
   - I told them not to continue, and that we would keep an eye on it and keep troubleshooting it (if neccessary) in the public eye on dspace-tech and Solr mailing lists
+- Testing an import of 1,429 Bioversity items (metadata only) on my local development machine and got an error with Java memory after about 1,000 items:
+
+```
+$ ~/dspace/bin/dspace metadata-import -f /tmp/bioversity.csv -e blah@blah.com
+...
+java.lang.OutOfMemoryError: GC overhead limit exceeded
+```
+
+- I increased the heap size to 1536m and tried again:
+
+```
+$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx1536m"
+$ ~/dspace/bin/dspace metadata-import -f /tmp/bioversity.csv -e blah@blah.com
+```
+
+- This time it succeeded, and using VisualVM I noticed that the import process used a maximum of 620MB of RAM
+
+## 2019-08-14
+
+- I imported the 1429 Bioversity records into DSpace Test
+  - To make sure we didn't have memory issues I reduced Tomcat's JVM heap by 512m, increased the import processes's heap to 512m, and split the input file into two parts with about 700 each
+  - Then I had to create a few new temporary collections on DSpace Test that had been created on CGSpace after our last sync
+  - After that the import succeeded:
+
+```
+$ export JAVA_OPTS='-Dfile.encoding=UTF-8 -Xmx512m'
+$ dspace metadata-import -f /tmp/bioversity1.csv -e blah@blah.com
+$ dspace metadata-import -f /tmp/bioversity2.csv -e blah@blah.com
+```
+
+- The next step is to check these items for duplicates
