## 2021-04-06
- Margarita from CCAFS was having problems deleting an item from CGSpace again
- The error was "Authorization denied for action OBSOLETE (DELETE) on BITSTREAM:bd157345-448e ..."
- This is the same issue as last month
- Create a new collection on CGSpace for a new CIP project at Mishel Portilla's request
- I got a notice that CGSpace was down
- I didn't see anything strange at first, but there are an insane amount of database connections:
```console
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12413
```
- The system journal shows thousands of these messages in the system journal, this is the first one:
```console
Apr 06 07:52:13 linode18 tomcat7[556]: Apr 06, 2021 7:52:13 AM org.apache.tomcat.jdbc.pool.ConnectionPool abandon
```
- Around that time in the dspace log I see nothing unusual, but maybe these?
```console
2021-04-06 07:52:29,409 INFO com.atmire.dspace.cua.CUASolrLoggerServiceImpl @ Updating : 200/127 docs in http://localhost:8081/solr/statistics
```
- (BTW what is the deal with the "200/127"? I should send a comment to Atmire)
- I file a ticket with Atmire: https://tracker.atmire.com/tickets-cgiar-ilri/view-tickets
- I restarted the PostgreSQL and Tomcat services and now I see less connections, but still WAY high:
```console
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3640
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
2968
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
13
```
- After ten minutes or so it went back down...
- And now it's back up in the thousands... I am seeing a lot of stuff in dspace log like this:

```
- I sent some notes and a log to Atmire on our existing issue about the database stuff
- Also I asked them about the possibility of doing a formal review of Hibernate
- Falcon 3.0.0 was released so I updated the 3.0.0 branch for dspace-statistics-api and merged it to `v6_x`
- I also fixed one minor (unrelated) bug in the tests
- Then I deployed the new version on DSpace Test
- I had a meeting with Peter and Abenet about CGSpace TODOs
- CGSpace went down again and the PostgreSQL locks are through the roof:
```console
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
12154
```
- I don't see any activity on REST API, but in the last four hours there have been 3,500 DSpace sessions:
```console
# grep -a -E '2021-04-06 (13|14|15|16|17):' /home/cgspace.cgiar.org/log/dspace.log.2021-04-06 | grep -o -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l
3547
```
- I looked at the same time of day for the past few weeks and it seems to be a normal number of sessions:
```console
# for file in /home/cgspace.cgiar.org/log/dspace.log.2021-0{3,4}-*; do grep -a -E "2021-0(3|4)-[0-9]{2} (13|14|15|16|17):" "$file" | grep -o -E 'session_id=[A-Z0-9]{32}' | sort | uniq | wc -l; done

```
- What about total number of sessions per day?
```console
# for file in /home/cgspace.cgiar.org/log/dspace.log.2021-0{3,4}-*; do echo "$file:"; grep -a -o -E 'session_id=[A-Z0-9]{32}' "$file" | sort | uniq | wc -l; done

- So it's not the number of sessions... it's something with the workload...
- I had to step away for an hour or so and when I came back the site was still down and there were still 12,000 locks
- I restarted postgresql and tomcat7...
- The locks in PostgreSQL shot up again...
```console
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3447
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
3527
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
4582
```
- I don't know what the hell is going on
- While looking at the logs I see that MEL is trying to log into CGSpace's REST API and delete items:
```console
34.209.213.122 - - [06/Apr/2021:03:50:46 +0200] "POST /rest/login HTTP/1.1" 401 727 "-" "MEL"
34.209.213.122 - - [06/Apr/2021:03:50:48 +0200] "DELETE /rest/items/95f52bf1-f082-4e10-ad57-268a76ca18ec/metadata HTTP/1.1" 401 704 "-" "-"
```
- I see a few of these per day going back several months
- Also annoying, I see tons of what look like penetration testing requests from Qualys:
```console

- I deleted the ilri/AReS repository on GitHub since we haven't updated it in two years
- All development is happening in https://github.com/ilri/openRXV now
