... folks... this evening one of our Maxen did some strange things and I tried so hard to track down what happened but couldn't find anything. There is a Max4k running 7.0.4 with a 16-S56 modem card and two PRIs. It's just taking calls and has a 8-port BRI-card additionally where two old ISDN PPP leased-lines are hooked up. At 7pm the following things happened and perhaps someone of you could get this puzzle together: - The Max stopped answering SNMP queries (MRTG) - The syslog is full of disconnections because "No NCPs were open" with state "IPNCP negotiation" - Nothing in the fatal log - The Max dropped his OSPF adjacency with a Cisco router several times - Even ONE (but only one of two) of the BRI-Leased lines flapped several times (with "No NCP open"). - Syslog shows some (but not much) "Radius client timeouts" although there is a secondary radius server available - Customer calling and complaining that there was no connection to the internet. At 8:30pm (just before I got informed and was able to check things out) all went back to normal immediately. The sessions came back up, all looks absolutely normal since then. I checked the MRTGs on the Cisco router infront of the Max to see whether there was a DoS attack with flood pings or anything else but the LAN was clean. Nothing special, no high traffic. Is here anyone who may at least guess what was going on? Thanks very much!
