Hi there,

I'm running netbsd 3.1 RC1 on TYAN S2881. It runs as a mailserver and if 
it comes to overload (cpu, mem, huge net traffic...), the system 
switches both ethernet cards (Broadcom BCM5704C) off for approx 10 min. 
Then it brings them back to functionality. I found this behaviour is ok 
but is there any possibility to switch off this "feature". If it is the 
kernel's job, isn't there any kernel configuration option to set up 
before compiling new kernel? Thanks. Pavel
