If you notice your site database growing faster than it should, please check the following:
- If you leave the page caching feature turned on, make sure that you have the Expire Page cron running.
Make sure that the Expire Page cron is running at least daily--otherwise every page ever viewed will be cached in the database. Running this cron daily will help to keep the database size small.
- Switch to using a real cron job.
The internal cron jobs won't work well with large databases as it executes them via PHP. On most servers, a PHP script will time out after 30 seconds.
- Try removing, then re-adding, the cron job.
If these suggestions don't help fix your suddenly-large database, please post a message on the main FusionBB website. We'll help you explore other possible causes/solutions.
