Database is locked

[dmshimself]

Since 11.2, I get some of the following from time to time, but I'm not sure that's OK or there is something I can configure my way around to avoid them. I usually get a cuple fo them a minute apart. Any thoughts appreciated.

Code:

Gone alerts:
* Unable to run alert source 'VolumeStatus'
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/django/db/backends/utils.py", line 64, in execute
    return self.cursor.execute(sql, params)
  File "/usr/local/www/freenasUI/freeadmin/sqlite3_ha/base.py", line 412, in execute
    execute = self.locked_retry(Database.Cursor.execute, query, params)
  File "/usr/local/www/freenasUI/freeadmin/sqlite3_ha/base.py", line 403, in locked_retry
    raise e
  File "/usr/local/www/freenasUI/freeadmin/sqlite3_ha/base.py", line 389, in locked_retry
    rv = method(self, *args, **kwargs)
sqlite3.OperationalError: database is locked

The above exception was the direct cause of the following exception:

This was a bug that will be fixed in the next update (due out on the 11th).

Great news and thanks for letting me know so quickly.
