[MapProxy] Seeding problem

[gdis at arcor.de]

Hi,

we have installed MapProxy several times now. When running the seeding tool, it often fails with the following error:

ValueError: (22, 'Invalid argument')

You can restart the tool and it will continue. But it often fails with the same error message a few minutes/hours later.

Any one has an idea what might be the problem?

Thank you very much.
