Jeff,

Are you jumping from VAX to Itanium, or do you have any Alphas around?

Do you have the Alpha-to-Itanium binary translator?

Craig Berry, have you run freetds on Itanium?

I'm wondering if we might be hitting an Itanium-specific bug. (Compiler?)

Craig

The systems are on the same subnet. I'm not local to the systems and I
haven't yet got the map showing what other active switching gear may be
between the two systems.

Yes. The Sybase connect is done at the beginning of the program and is
attached continuously. As I've mentioned in previous messages, this
program is currently running on our VAX environment with the original
Sybase client. The program can run for months without failure.

We've hunted around for some type of automated connection killer that
might be running, but we've found none. As this test DB is on the same
server as the production DB, it seems doubtful.
