Strange Behavior

I have installed the DSS on several platforms for comparison and am seeing something strange happening on the version that is running on linux.  I noticed that the stream dies periodically.  In VLC the stream simply hangs.  In quicktime, the stream dies briefly, then you see quicktime establish a new rtsp connection and the stream picks up where it left off.

 

We attached a debugger to the process and this is what we saw:

 

Program received signal SIGFPE, Arithmetic exception.

        delta = 999

        theTime = 0

        bits = 0

        numProcessors = Variable "numProcessors" is not available.

 

Now I looked at the code and I am not sure what is happening (I am not a C++ programmer) but if delta is less than zero then the following line will cause theTime to be equal to 0:

 

        UInt32 theTime = delta / 1000;

 

If theTime equals 0 then line 423 will fail everytime:

 

        packetsPerSecond /= theTime;

 

The following code inplies you are aware of the problem but other than the warning no excpetion handling occurs:

 

        if (delta < 1000)

            WarnV(delta >= 1000, "Timer is off");

 

Am I reading this right or is their another reason why the code might be failing at this line?

 

Thanks for your help.

 

Sincerely,
