## 2018-01-02
- Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time
- I didn't get any load alerts from Linode and the REST and XMLUI logs don't show anything out of the ordinary

2018-01-02 18:30:34 +01:00
- The nginx logs show HTTP 200s until `02/Jan/2018:11:27:17 +0000` when Uptime Robot got an HTTP 500
- In dspace.log around that time I see many errors like "Client closed the connection before file download was complete"
- And just before that I see this:
```
Caused by: org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-980] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:50; busy:50; idle:0; lastwait:5000].
```
- Ah hah! So the pool was actually empty!
- I need to increase that, let's try to bump it up from 50 to 75
- After that one client got an HTTP 499 but then the rest were HTTP 200, so I don't know what the hell Uptime Robot saw

- I notice this error quite a few times in dspace.log:
```
2018-01-02 01:21:19,137 ERROR org.dspace.app.xmlui.aspect.discovery.SidebarFacetsTransformer @ Error while searching for sidebar facets
org.dspace.discovery.SearchServiceException: org.apache.solr.search.SyntaxError: Cannot parse 'dateIssued_keyword:[1976+TO+1979]': Encountered " "]" "] "" at line 1, column 32.
```
- And there are many of these errors every day for the past month:
```

- Danny wrote to ask for help renewing the wildcard ilri.org certificate and I advised that we should probably use Let's Encrypt if it's just a handful of domains
