I have an issue that I have not seen before. I am a beginner with SQL server so I have tried what I know but no success. I have SQL 2005 SP3 (9.00.4035.00) on one of the SQL DB servers. There are two databases on this server. I have noticed that for last 2 weeks or so the .ldf file grows but the .mdf file will only get modified once if that. I have had to backup the DB and then truncate the log file as it starts throwing tran log full errors. I ran consistency checks on the DB (DBCC checkdb(test)) and no errors found. I tried to change the recovery model from "Full" to "Simple" and back to "Full". This has not helped. Has anyone see this before. I would appreciate any assistance with this.
