Today at our Datacenter there was a very strange issue. So we were seeing many drops with servers that we had on one of our many cirucits. Only one circuit was affected. After troubleshooting through everything I realized that the issue was PIX that we have on that circuit. When everything else except this PIX is connected in everything works fine. This has been our PIX for the last 3-4 years and has worked just fine. Out of nowhere now it basically takes down everything. No changes were made and this just happened out of nowhere. What I mean by it takes down everything is that we have basically a public switch with a few devices into it. All of these devices work 100% when I unplug the PIX from it however when I plug the PIX everything completely loses connection. By this I mean that 50% of pings to ALL devices including the PIX itself fail but again once I disconnect the PIX everything comes completely up again. Just to reiterate this has been our PIX for the last 3-4 years and no changes were made. This happened out of nowhere. Has anyone ever seen anything like this and do you think there is a way to fix or should we just simply replace?
