 - For what it's worth, we have been setting the actual Tomcat 7 process' limit to 16384 for a few years (in `/etc/default/tomcat7`)
 - Looks like cron will read limits from `/etc/security/limits.*` so we can do something for the tomcat7 user there
 - Submit pull request for Tomcat 7 limits in Ansible dspace role ([#30](https://github.com/ilri/rmg-ansible-public/pull/30))

+- Reduce Amazon S3 storage used for logs from 46 GB to 6GB by deleting a bunch of logs we don't need!
+
+```
+# s3cmd ls s3://cgspace.cgiar.org/log/ > /tmp/s3-logs.txt
+# grep checker.log /tmp/s3-logs.txt | awk '{print $4}' | xargs s3cmd del
+# grep cocoon.log /tmp/s3-logs.txt | awk '{print $4}' | xargs s3cmd del
+# grep handle-plugin.log /tmp/s3-logs.txt | awk '{print $4}' | xargs s3cmd del
+# grep solr.log /tmp/s3-logs.txt | awk '{print $4}' | xargs s3cmd del
+```

+- Also, adjust the cron jobs for backups so they only backup `dspace.log` and some stats files (.dat)
