Groupstudy board, I have a really annoying problem that I hope you can help me with. I have 2 8540's liked by a GigE link at the core of my network and one switch is having severe underrun problems on most interfaces (esp. the Gig links). Have any of you had the same problem and what fixed it? The TAC has basically told me to replace the long wave GBIX cards as a first step. The bottom line is that it seems like each underrun causes a TCP reset, which messes up anyone with keep alives on, which may be causing me no end of headaches with any high availabilty apps.
