HI Ian, first place to look is in the /var/logs (console.app) and use the global search for COMPRESSOR.app to see if its a UI issue. It maybe from another components. The logs SHOULD show this error. YOu may have to dig around a abit. Use the 'Find command now in console.app too)
YOu might want to consider upgrading the OS to something current if you can. 10.6.8 may be stable however the interation of the latest Compressor and Qmaster etc wit hthose frameworks etc in MACOSC 10.6.8 may not be clean.... just a guess too.
Do you have Little Snitch.app installed and activated on this host? This is usually ok, however Qmaster may be asking the outside world for a look? could be. Little Snitch may have barred him form doing this.. just a thought. Litt;e Snitch message usually stay up in its UI.... just a guess.
If the job is running and the backend is flashing these messages then search for QMASTER. You may also have DNS error message if your cluster is out hunting for other nodes.
IF you are using QMASTER (submit with batch), then you might want to check the logs of those services via the SHARE MONITOR... I'd that this is not the source.
The parms are not this issue me thinks.
TRy this when you have time if you DONT need QMASTER on another host.
Step 1: quiesce/ shutdown anything but COMPRESSOR and Qmaster.
Step 2: turn off / disable you network on your mac. (use system prefs/network/ create a new SETTING "no network" and delete all the NICS.. apply this... = no network.
Step 3: submit your batch again and determine the results
See if you still get these flashing messages....
IF not, then resinate your network (pull up the default system prefs settings for network) and apply.
Post your results for others to see.
