I need to know WHAT MESSAGE WAS SUPPRESSED. I am getting slammed. My server will display anywhere from a few hundred to 50K messages suppressed. Previous posters have suggested that if I go early enough in my logs, that I will find the original suppressed message. NOT TRUE. I am desperate. These messages are an indication of a larger problem, but I am unable to diagnose what. My network is fairly small (650 nodes), and I have been receiving these messages time and again. Sometimes every 3 hours, sometimes every 3 days. Network analizers (Ntop, iptraf) have been unable to identify the source of the traffic. If I run these utilities on the server, they freeze (while a flood is going on). If I run the utilities on a different computer on a port of the switch, they don't see the traffic intended for the server (obviously). If I configure the switch for a "monitor" port (one that sees all traffic) and plug a different computer on that port, then that computer freezes too, along with the server. The few times that we cought a machine WHILE it was generating the traffic, we could not find any evidence of wrongdoing. No viruses, no trojan horses, no smoking gun. The ONLY mechanism that stops the traffic is blocking ARPs at the switch. But I feel that ARP is another symptom, not the actual problem (like an ICMP flood). The switches used are 12x HP J4121A (Procurve 4000M) and one HP5308XL (fiber cross-connect). Once the Linux router gets slammed, it is a matter of time before it freezes and dies. ANY help would be appreciated. Here is a sample: **** [root@ess-uvce root]# grep "kernel: NET" /var/log/messages; Oct 21 15:34:00 ess-uvce kernel: NET: 205 messages suppressed.
