[Tue Jul 31 00:00:41 2018] oom_reaper: reaped process 1394 (java), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB
```
- Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight
- From the DSpace log I see that eventually Solr stopped responding, so I guess the `java` process that was OOM killed above was Tomcat's
- I'm not sure why Tomcat didn't crash with an OutOfMemoryError...
- Anyways, perhaps I should increase the JVM heap from 5120m to 6144m like we did a few months ago when we tried to run the whole CGSpace Solr core
- The server only has 8GB of RAM so we'll eventually need to upgrade to a larger one because we'll start starving the OS, PostgreSQL, and command line batch processes
- I ran all system updates on DSpace Test and rebooted it
- I started looking over the latest round of IITA batch records from Sisay on DSpace Test: [IITA July_30](https://dspacetest.cgiar.org/handle/10568/103250)
- incorrect authorship types
- dozens of inconsistencies, spelling mistakes, and white space in author affiliations
- minor issues in countries (California is not a country)
- minor issues in IITA subjects, ISBNs, languages, and AGROVOC subjects
- DSpace Test crashed again and I don't see the only error I see is this in `dmesg`:
```

```
- I am still assuming that this is the Tomcat process that is dying, so maybe actually we need to reduce its memory instead of increasing it?
- The risk we run there is that we'll start getting OutOfMemory errors from Tomcat
- So basically we need a new test server with more RAM very soon...
- Abenet asked about the workflow statistics in the Atmire CUA module again
- Last year Atmire told me that it's disabled by default but you can enable it with `workflow.stats.enabled = true` in the CUA configuration file
- There was a bug with adding users so they sent a patch, but I didn't merge it because it was [very dirty](https://github.com/ilri/DSpace/pull/319) and I wasn't sure it actually fixed the problem
- I just tried to enable the stats again on DSpace Test now that we're on DSpace 5.8 with updated Atmire modules, but every user I search for shows "No data available"
- As a test I submitted a new item and I was able to see it in the workflow statistics "data" tab, but not in the graph
