Sorry I can't solve your problem (too technical for me) but I have notes on the testing code.

It makes things hard to read and dependent on architecture details, i.e. the width of an int. The time argument should be an integer specified in a human-readable manner, i.e. decimal. If you want to turn timeouts off, specify zero or a negative number. If you want to specify a specific value like 15 minutes then writing "15*60*1000" explains to anyone reading your code what you're doing and what you think you're doing. > sqlite3_exec(db, "PRAGMA PRAGMA wal_autocheckpoint = 0;", NULL, NULL, NULL) Is "PRAGMA PRAGMA" a copy/paste error ? Given how specific you are about your configuring I am surprised you don't declare PRAGMA threads = N Are each of your thread using their own handles or do they all share the same handle ?
