It looks like it is just a simple logfile where it writes down what it is doing when it is called.
It is called when Poser is started to initialise itself and writes down the timestamp. If you don't use DSON, that's it. It doesn't send it anywhere, it is just a help file to assist them in sorting out problems. Almost every program has something like this, it is usually turned off by default when a program is matured. In the introduction phase, it is often turned on for trouble shooting.

And it is not running all the time, it is just logging what it is called to do and does not do anything when it is not called,

So nothing to worry about.
