[AG-TECH] vic gui freezes...

[M.Sczimarowsky]

Hello everybody,

we are trying to fix a problem, that we are facing since the very
beginning of our AG activity, and that stayed with us throughout various
changes in AG software and OS releases:
whenever we start several vic instances on our capture machine with the
AG default frame rate / bandwidth values, the gui freezes after some
seconds. Video transmission is ok, but we have no chance to change the
settings of a specific video stream unless we restart the vic. 
The problem disappears when we start with the low transmission/frame
rates of the ucl-vic defaults.

conflicting interrupts dont seem to be a problem here: 

ag at ag-vin:~> cat /proc/interrupts 
           CPU0       CPU1

We are currently running SuSE. 7.3 on a dual Pentium III 866 MHz, but we
observed the same problems under the AG RedHat Release.

Any help would be greatly appreciated.

Martin
