Perhaps FreeBSD does not implement recursive mutexes. In that case, you can try to recompile with -DSQLITE_HOMEGROWN_RECURSIVE_MUTEX=1 and see if that helps. It would be good to review the comments in mutex_unix.c to see if the HOMEGROWN_RECURSIVE_MUTEX implementation really is safe for FreeBSD. D.
