this ms access db taking long time to close what is the reason and how to solve this problem ?
Check what your database is doing.
If a lot of time is required, there may be a lot of work to be done at that point
- close open objects
- Unload data somewhere
- backups and exports to the outside world
=> open objects should be closed as quickly as possible, not just at the end
=> It's better to only load the data that you really need
You should also determine who the database is communicating with. Unnoticed queries from an Excel workbook or a missing or delayed answer from the internet can quickly trigger a wait.
What does the developer of the database say about the behavior in question?
