I have a Windows-based master and a single OSX client. Builds are run on the OSX client using the Jenkins slave agent which is launched manually by downloading and running the appropriate jnlp file from the master web server.

Once running, builds and notifications progress as expected.

However, approximately once a day - usually overnight when no builds are running, the slave agent closes. Sometimes when I go to check it just isn't running any more, once or twice it has crashed. I'm intending to gather more information next time a crash occurs, although typically since deciding to do this it has just been closing 'cleanly'.

Unfortunately I'm not entirely sure when this started to happen as there was an extended period of one project being left in a 'known broken state', resulting in Jenkins getting turned off.

Any suggestions on how to fix this situation would be much appreciated.
