It is used to deal with bulk transaction processing, business programs, and content management. The Microsoft SQL server is chosen for its high-level security, scalability, and performance. Sometimes, corruption in the SQL database occurs due to the saving of a large amount of business information. This problem makes the server inaccessible, flashing an error message on the window.

Following are those additional causes of SQL server error 3403 :
  • While updating the allocation page, the data gets written on the transaction log before the crashing takes place.
