I have managed (with a lot of effort) to track down the apparent cause
of the regression failures I was seeing. They appear to be directly
related to the degree of parallelism with which the tests are run. I can
reliably get a 100% clean run on the serial tests, and on the parallel
tests with MAX_CONNECTIONS=5. But if I run at MAX_CONNECTIONS=10 I
(almost) always get failures, which for some reason that is beyond me
start with the copy test, which isn't even run in parallel with other tests.

This is all quite worrying, and suggests that we will need to do some
careful stress testing before we can release this.

Is there some W2K parameter I can tweak in the TCP stack that might
alleviate the problem?

Cheers

andrew
