[syslog-ng] syslog-ng.persist file error

Hello, When I came in this morning, syslog-ng was not running, and the following error is produced when trying to start it with init script:

Error loading persistent configuration file; name='//var/syslog-ng.persist'

I'm guessing that additional forward slash is not supposed to be there, but I have no idea how this is getting set or where to change it. Can anyone help me? Thanks, Scott
