Can't answer your question, but …
If you're getting unexpected locks, have you set a timeout on every connection
to that database ? That gets rid of most locks.

Hello
Is it possible to get a C# exception when the error
SQLite error (5): database is locked occurs?
I am using the entity framework with multiple thread and a global mutex.
I would like to know which call generates the locking error.
Thanks

Does setting the busy_timeout retry periodically (e.g. every x milliseconds),
or is there some automatism that ensures that the requested operation is done
just-in-time as soon as the previous/blocking operation is finished?

Hallo
I use several tasks in C# to call Sqlite queries.
No I get the error SQLite error (5): database is locked.
Is it not possible to use more than one tasks with Sqlite?

Hi all,
I am using System.Data.SQLite in my project.
I have two threads which are updating database simultaneously.

Why is it so!. What could be the reason? Does System.Data.SQLite is not
thread safe?
Please help me out
