- Abenet was asking if there was some way to hide certain internal items from the "ILRI Research Outputs" RSS feed (which is the top-level ILRI community feed), because Shirley was complaining
- I think we could use `harvest.includerestricted.rss = false` but the items might need to be 100% restricted, not just the metadata
- Adjust Ansible postgres role to use `max_connections` from a template variable and deploy a new limit of 123 on CGSpace
## 2017-08-17
- Run Peter's edits to the CGIAR System Organization community on DSpace Test
- Uptime Robot said CGSpace went down for 1 minute, not sure why
- Looking in `dspace.log.2017-08-17` I see some weird errors that might be related?

- There are none in 2017-07 either...
- A few posts on the dspace-tech mailing list say this is related to the Cocoon cache somehow
- I will clear the XMLUI cache for now and see if the errors continue (though perpaps shutting down Tomcat and removing the cache is more effective somehow?)
- We tested the option for limiting restricted items from the RSS feeds on DSpace Test
- I created four items, and only the two with public metadata showed up in the community's RSS feed:
- Public metadata, public bitstream ✓
- Public metadata, restricted bitstream ✓
- Restricted metadata, restricted bitstream ✗
- Private item ✗
