I had an issue last night with a fairly new s8400. All the IP sets continued to worked but the connection to IA770 failed. I could ping all the IP bound cards but any sort of connection to them failed. ASA failed and the web gui connection failed. A bounce cleared all problems and no visible logs to explain the failure. It was like a port failure or blockage. Any insight on this issue to help me prevent it from happening again would be greatly appreciated. Thanks.
