Hi Ricky,
CA Spectrum asserts the "DEVICE HAS STOPPED RESPONDING TO POLLS" alarm when the device is not responding to PING.
Did you test the Ping from the SpectroSERVER machine?
Does this problem happen to a specific device?
What is the CA Spectrum version? Check the $SPECROOT/Install-Tools/.history file.
What is the Operating System? Windows? Linux? Solaris?
Thanks,
Silvio
