What you did there was the absolute, very, final last resort for this kind of problem. You could have transactional inconsistencies, you could have structural inconsistencies.

Stuff that needs doing:

Run CheckDB with no_infomsgs and all_errormsgs and hope there are no errors

Sort out your log maintenance. See - Managing Transaction Logs[/url]
