ReadyAPI Runner on Jenkins writes logs in the home directory how do I clean up?

We use a ReadyAPI Runner on our Jenkins slave and we have seen that the runner writes his own log for every Job that it running. The log is located in the <home directory>/.readyapi directory, where we have a reduced space to write something. After a while the node will be unusable because the logfiles will exceed the space available. 

In the documentation I did not find an option to specify not to write logs there or a different location. How can I tell the runner not to write logs or write them elsewhere?

I'm running on linux, the used readyapi version is at 2.6.0 at the moment.
