Hello, Recently we have been experiencing some problems with the network dying temporarily on a machine then magically coming back to life. This appears to happen more frequently when the machines are loaded down CPU wise and usually sustain over 3Mbits/sec of network traffic. This is happening on several machines with similar configurations. Each machine has about 2000 active tcp connections on them and CPU usage is typically over 75%. They have AMD 800-950 processors and 3Com 905C cards running Redhat 6.2 with kernel build ranges from 2.2.17p3 to 2.2.18p10.
When this happens the below logs appear in the system logger:
