This is a log from when the database seems to 'lock up', apparently refusing to load tiles it has already downloaded. I'm not 100% sure how to trigger it, but generally scrolling around and zooming in and out in an area I haven't yet downloaded works reliably eventually. I've left it in that state for 1/2 hour probably, and it doesn't recover - though interestingly, it does seem to be able to load other tiles sometimes (e.g. if I zoom really far out) - it just seems to choke on certain particular areas of map, but after closing the program and relaunching it, and sometimes even just by zooming out then back in again, those areas of map will draw fine.

Quite a few examples of this:

Code:
Traceback (most recent call last):
  File "modules/gui_modules/gui_qt5/gui_qt5.py", line 302, in _selectImageProviderCB
    return self._imageProviders[providerId].getImage(imageId, requestedSize)
  File "modules/gui_modules/gui_qt5/gui_qt5.py", line 599, in getImage
    log.exception()
TypeError: exception() missing 1 required positional argument: 'msg'

    tileData = self._storeTiles.getTileData(lzxy)

    return self._getTileDataFromSqlite(lzxy)
  File "modules/mod_storeTiles.py", line 385, in _getTileDataFromSqlite
    result = self.getTileFromDb(lookupConn, dbFolderPath, lzxy)
  File "modules/mod_storeTiles.py", line 455, in getTileFromDb
    (z, x, y))
sqlite3.OperationalError: database is locked
And probably less important, but nevertheless rather saddening to read, this too:

NOTE: this probably means that the tileserver returned an
error page in place of the tile, because it doesn't like you
