I had a strange problem with the redundancy between two of my CSS11000.
They were both master at the same time. With resulted in total apocalypse :(

Just before CSS01 switched to backup mode I see it saying SNTP-6: No SNTP replies in 3*poll-interval secs. When CCS01 switches back to master mode I can see this same message on my CSS02. But I dont see the CSS02 switching back to backup mode. So they where both master at the same time and it was disaster time.
When I logged in and saw the problem, I rebooted CSS02. After the reboot the situation restored itself. But I now need to find out why it happened and how to prevent this to happen in the future.
The only thing I can see is the SNTP errors. Does anyone has any idea why this happened and could this be a result of the SNTP errors. If you need additional information just let me know.
