Bandana table size exploding

Question

Hi, yesterday we noticed our database server was running out of space. Upon further inspection we found the bandana table to hold more than 3 million entries with +3GB size. After restarting confluence the table went back to "normal" with ~8MB and 1500 entries.

Anyone knows what might have happened here?

Hi,

As Matthew said, seems that some third-party plugin is creating several entries on that table.

Next time it happens, try to:

1) create a database dump;

2) Restart Confluence;

3) Create another database dump;

4) Make a diff be dumps regarding the Bandana table entries;

This will allow you see clearly which plugin is creating this.

Hope it helps with the troubleshoot!

Many of the third party plugins write to the bandana table and it can grow quickly. I would start by looking at the entries to see if there are any clues. Barring that, start disabling third party plugins until performance improves.

The user rating plugin is particularly bad when it comes to creating bloated entries.
