On Monday we suffered a full scale system overload due to onboard gig ethernet adapters. We switched to a 3com PCI 3C905CX-TX-NM and most of the problems have gone away.
We are still having problems where the processor will flatline at 100% for between 1 and 3 minutes at a time. This happens primarily when the single large list that we host (120 users) gets a message, about every 10 or 20 minutes. When the processor flatlines, users will have hangs of up to 60 seconds sending or receiving mail. A call to Ipswitch resulted in the discovery that our logs contain about 1400 type 10054 errors on a daily basis. Ipswitch believes that all my problems revolve around these 10054 errors, and that if I can get rid of these errors, my processor max out problem will also stop. They recommended a network sniffer called Ethereal to track down the cause of the 10054 errors. We haven't the faintest idea of where to go with this problem, or what we should do with the data that Ethereal gives us. Has anyone found a solution that gets rid of these 10054 errors? Any help is appreciated.
