Hello all,
We have an application running over samba share that creates a lot of 0-length
files, and eventually throws an error because one of more of the files could not
be created or does not appear to be created.
At the same time in the samba log there are many messages like

There is no other errors.

Any idea what could be the problem?
Thanks
