Fascinating. Okay, first try changing the DB_NAME to something else. If the
original is a file on a network share, try a local file. Or try a file in your
home folder. Or try a SQLite database in memory.
Another approach is to omit the _close. Just for your test application. Or
put the _close after the ping_server. I know it's bad programming but there's
no actual code there anyway. See if it's the _open or _close that's the
problem.
If neither of these give you a clue to the problem you could possibly copy the
sqlite3 functions from the source code and include them specifically into your
source code. Then start stripping the functions themselves down to the bare
bones.
