Great information, thank you very much.
I changed the instances to 8 (I have 16 GB ram) not sure what that does but it seemed to work ok.
I created a dvd by dragging a file to compressor I failed to uncheck share monitor so that came up but it seemed to work ok.
I went from fcpx to compressor and it handled the file ok (I had unchedked the share monitor before doing this)
I left rendering unchecked, again not sure what difference that makes but it worked ok.
Thanks for your help
Hi glenn thanks for the comments. Just to be clear for anyone who has a similar situation, does the problem you initially experienced still exist?
Also no need to start RENDERING services in Qmaster if you are not rendering with shake etc. just set Qmaster up for transcoding (compressor)
Additionally the share monitor.app is not so stable however it can be relied on it does have a clean Qmaster foundation such as I've described in many posts. Share monitor has regular "heart attacks" when it can't get cluster information over sockets in a timely fashion.
Just restart it.
Glad to see you are working again.
