As usual I came yesterday to my office and opened the mail then I found mail from client say “very urgent- CMS error” opppppppppps, site is up and running since 6 months so what happen?
So I told them that the problem will be one of the following
1 – Transaction log reached very big size and I recommended to them these articles
Microsoft.com
http://www.banmanpro.com/support/logfiles.asp .
Finally the error was because they did replication to the database.
