Relying on JS to step in and clarify...but, as I understand, the superserver version doesn't scale well and you get a "see-saw" effect as bunches of threads get swapped back and forth between the CPUs. If InterServer isn't threaded, then my shot in the dark could very well be astray. The problem is with SS on any platform and it doesn't exist with Classic, AFAIK.

I haven't heard that the problem affects clients and don't know why it would. I don't understand what you mean by "InterServer on a machine not running the database itself". Are you saying that you are running the server on one machine and physically storing the database on another? Pardon my ignorance about InterServer - so far I've assumed it's a Java version of IBServer that would be subject to the same physical restrictions but I could be way off mark on that.

>c) How do I set the affinity?

There's a freeware utility for Windows, written by (I think) Martijn Tonies. http://www.ibobjects.com/ib_affinity.zip

YES. The etiology is ..well... very similar to what you described but the dropouts in this case were random and affected active and idle connections indiscriminately. Hope that it is configuration problem because identifying and eliminating faults in the network is hell, especially if you bought a bad batch of something, where some might be OK and some might be bad.
