[web2py] sqlite OperationalError: database is locked in a cron job

[Pablo Angulo]

Hello: I'm working on a cron job that must write to the database: is
this allowed? I don't know if the following error is sqlite only:

  File "web2py/gluon/dal.py", line 4487, in insert
    return self._db._adapter.insert(self,self._listify(fields))
  File "web2py/gluon/dal.py", line 772, in insert
    raise e
pysqlite2.dbapi2.OperationalError: database is locked

Regards
