I little bit frustated
after getting no luck with Pyun YongHyeon patch, i run cvsup today and
going to see what happen tomorrow.
It's happen only on bussy hour/work hour but not on afternoon until
morning. it's mean only happen when on maximum/heavy traffic load.
I suspected it's error on motherboard or the system.
now i'm using 2 ethernet using 2 different catalyst switch and 2 different network.
