## 2018-01-10
- I looked to see what happened to this year's Solr statistics sharding task that should have run on 2018-01-01 and of course it failed:

- DSpace Test has the same error but with creating the 2017 core:

- There is interesting documentation about this on the DSpace Wiki: https://wiki.duraspace.org/display/DSDOC5x/SOLR+Statistics+Maintenance#SOLRStatisticsMaintenance-SolrShardingByYear
- I'm looking to see maybe if we're hitting the issues mentioned in [DS-2212](https://jira.duraspace.org/browse/DS-2212) that were apparently fixed in DSpace 5.2
- I can apparently search for records in the Solr stats core that have an empty `owningColl` field using this in the Solr admin query: `-owningColl:*`
- On CGSpace I see 48,000,000 records that have an `owningColl` field and 34,000,000 that don't:
```
$ http 'http://localhost:3000/solr/statistics/select?q=owningColl%3A*&wt=json&indent=true' | grep numFound
"response":{"numFound":48476327,"start":0,"docs":[
$ http 'http://localhost:3000/solr/statistics/select?q=-owningColl%3A*&wt=json&indent=true' | grep numFound
"response":{"numFound":34879872,"start":0,"docs":[
```
- Linode continues to test mitigations for Meltdown and Spectre: https://blog.linode.com/2018/01/03/cpu-vulnerabilities-meltdown-spectre/
- I rebooted DSpace Test to see if the kernel will be updated (currently Linux 4.14.12-x86_64-linode92)... nope.
- It looks like Linode will reboot the KVM hosts later this week, though
