I think my database is corrupt, please see error below. I've tried to run the suggested commands but it would hang sql then eventually server. Certain queries against this DB will now hang SQL. Running a backup of the database will also hangup SQL. The database is 15GB with a 31GB ldf file. I don't have a good backup. I can't take the database/server down for a long period of time as this is a 24/7 production server. I'm thinking of taking the DB offline and copying the 2 database files to a backup server and attempt to rebuild. However, because the DB is somewhat large, I'm afraid taking it offline may also crash SQL. Does anybody know of a better options to recover from this error?
