A suggestion from the News Forum: some disk space could be freed up by deleting some the older task records. E.G., I have almost 5 months-worth, some 1600+ task records, most of which could be deleted. I'd be happy with just the past couple of weeks of task records.

People with millions of credits, do you have thousands of old task records?

As I have written in another thread, this is not problem. Task records older than 90 days are archiving. Task records are only in database and archived in xml.gz files. Size of database is currently 18.8 GB and archived records have 4.9 GB so this is really not problem.
