- Discuss RSS issues with IWMI and WLE people
## 2018-12-06
- Linode sent a message that the CPU usage of CGSpace (linode18) is too high last night
- I looked in the logs and there's nothing particular going on:

```
- `54.70.40.11` is some new bot with the following user agent:
```
Mozilla/5.0 (compatible) SemanticScholarBot (+https://www.semanticscholar.org/crawler)
```
- But Tomcat is forcing them to re-use their Tomcat sessions with the Crawler Session Manager valve:
```
$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=54.70.40.11' dspace.log.2018-12-05
6980
$ grep -o -E 'session_id=[A-Z0-9]{32}:ip_addr=54.70.40.11' dspace.log.2018-12-05 | sort | uniq | wc -l
1156
```
- `2a01:7e00::f03c:91ff:fe0a:d645` appears to be the CKM dev server where Danny is testing harvesting via Drupal
- It seems they are hitting the XMLUI's OpenSearch a bit, but mostly on the REST API so no issues here yet
- `Drupal` is already in the Tomcat Crawler Session Manager Valve's regex so that's good!
