## 2016-05-01

- Since yesterday there have been 10,000 REST errors and the site has been unstable again
- I have blocked access to the API now
- There are 3,000 IPs accessing the REST API in a 24-hour period!

```
# awk '{print $1}' /var/log/nginx/rest.log  | uniq | wc -l
3168
```

- The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29
- 100% of the requests coming from Ethiopia are like this and result in an HTTP 500:

```
GET /rest/handle/10568/NaN?expand=parentCommunityList,metadata HTTP/1.1
```

- For now I'll block just the Ethiopian IP
- The owner of that application has said that the `NaN` (not a number) is an error in his code and he'll fix it

- Update nginx to 1.10.x branch on CGSpace
- Fix a reference to `dc.type.output` in Discovery that I had missed when we migrated to `dc.type` last month ([#223](https://github.com/ilri/DSpace/pull/223))

- DSpace Test is down, `catalina.out` has lots of messages about heap space from some time yesterday (!)
- It looks like Sisay was doing some batch imports
- Hmm, also disk space is full
- I decided to blow away the solr indexes, since they are 50GB and we don't really need all the Atmire stuff there right now
- I will re-generate the Discovery indexes after re-deploying
