Do these threads finish calling this database method before they call it again? And if they finish, do they close the resources properly? If not then you're probably running out of connections.

What connection pool API are you using? You probably ran out of connections. Check two things:

a) You don't have too many connections open
b) You don't have too many transactions (that hold db connections) still running. Make sure that you always end your transactions.

We are not using any api for database connection pool .
we are just using "DB.execSQL("BEGIN TRANSACTION");" and "DB.execSQL("END TRANSACTION");"  in a database method . This database method is called from two background thread repeatedly .

What do these two threads do? Do they update the same table? There might be a deadlock involved.
