I have some great news for our Backburner users who are running into issues submitting jobs from Maya. We have just posted a public release of Backburner 2012.1.1. There are some key fixes and I highly recommend you upgrade if you are running into any of the issue listed below.
The download can be found in the Autodesk.com site here.
I highly recommend you uninstall the current version and remove all Backburner preferences before installing the newest cut.
After you install and get backburner up and running attempt to submit a job. If you still seem to be getting a connection refused error when submitting a job, try entering 7347 as the port value and submit again.
Setting this value will pass the default setting where cmdjob uses multicast to connect to the manager and fails.
|MAYA-7652||No connection could be made, target machine refused error while submitting a job or if a port was manually entered in the Submission window|
|MAYA-8238||Manager fails to launch with machines with multiple network adapters|
|MAYA-8117||Problem closing Manager on Windows 7 64-bit operating system|
|MAXX-4177||Manager creates duplicate job handles when multiple jobs are sent within one second of each other|
Best of luck!
