I know I wouldn't put a 8131 on a production server, unless I have no choice. This comment is from /sys/pci/if_rl.c: * * The RealTek 8139 PCI NIC redefines the meaning of 'low end.'

Re: 3c905B drivers
Hi, I have had two instance's when using the 3com card that the bsd box reboot's, when transferring alot of data to it. I have also had machine's complete lockup.

A 3COM 905B cards, something like this. It was corrected in rev. B or by a firmware/flash upgrade of some sort. You might want to look into this, though on the other I am not at all sure about this information...

I'm using them on several clients, wiht squid/samba/ipfilter/sendmail/apache and never had a problem. The networks are mid-sized (300 to 1000 hosts). You can do some research to find the problem: 1. search the logs. 2. Run ps/vmstat/iostat/netstat to see what happens. 3. Take a look at the -i and -m flags to netstat 4. Read tuning(7). You may need to tweak some things. 5. try a 'make buildkernel'. If there are some hardware problems, it will fail.
