Intermittent network issues with Freebsd 6.2

Hi All,

I am having intermittent network issues with our IBM X236 dual xeon server.
Server comes with two bge network cards. At random intervals internal lan
drops out. And then few minutes later it comes back online.

So far I can only find some interface errors on netstat -i. Can anyone help
me to resolve this issue.

Please refer to attached files and below outputs for more information.
