Are these safe to delete? My box has 173mb of "toplog.nnnnnnnnn" files dating back for many many months. Since my host is limited to 1500mb this is a significant disk-usage hit.
IMHO their value for postmorteming a dead vox will fade over time, so perhaps there should be a second cron job that deletes any toplogs that are older than a user-configurable age (e.g. one week, two weeks, one month, two months, etc.).
