- I told them that it's their JavaScript that is fucked up
|
||||
- Remove CPWF project number and Humidtropics subject from submission form ([#3](https://github.com/alanorth/DSpace/pull/3))
|
||||
- I accidentally merged it into my own repository, oops

## 2018-02-22
|
||||
|
||||
- CGSpace was apparently down today around 13:00 server time and I didn't get any emails on my phone, but saw them later on the computer
|
||||
- It looks like Sisay restarted Tomcat because I was offline
|
||||
- There was absolutely nothing interesting going on at 13:00 on the server, WTF?

- While looking at the logs I see some new bot:
|
||||
|
||||
```
|
||||
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.4.2661.102 Safari/537.36; 360Spider
|
||||
```
|
||||
|
||||
- It seems to re-use its user agent but makes tons of useless requests and I wonder if I should add ".*spider.*" to the Tomcat Crawler Session Manager valve?
|
||||
- This is definitely not good:
|
||||
|
||||
```
|
||||
# grep -c 'org.apache.tomcat.jdbc.pool.ConnectionPool abandon' /var/log/tomcat7/catalina.out
|
||||
729
|
||||
```
|
||||
|
||||
- I think the `removeAbandonedTimeout` might still be too low (I increased it from 60 to 90 seconds last week)
|
||||
- Perhaps something more like a few minutes is better?
