SQLite unlock database

Question

GRASS module crashed and left sqlite database locked. How can I unlock sqlite database?

Answer

Make sure the database file isn't read-only or that you don't have database already open by other application. E.g.

$ ps aux | grep sqlite
martin   21118  0.0  0.3  21456  3176 pts/1    S    Dec04   0:00 /usr/local/src/grass6_devel/dist.i686-pc-linux-gnu/driver/db/sqlite

To kill the process:

$ kill -9 21118
