I have a site in drupal, at times its really slow have to reboot the server.
I see mysql is consuming too much resources.
I have a core table for drupal devel_times: it contains over 846,000,000 rows and the table itself is about 30 Gb, is that not causing the problem, because I see each time it logs entries, can I empty that table?
Even if this issue is related to drupal 5, I think it's still valid. So I would definitely say yes, you can delete those records :)
