The TDS protocol was originally limited to one statement handle per database connection. You can see the same issue with DBD::Sybase using the Sybase client.

In some cases (specifically when using a cursor on a query rather than a "normal" stream request) TDS will allow more than one open statement handle (at least with Sybase open client).

I suspect that FreeTDS may be more limited in this case than the native MS client.

PS - DBD::Sybase has a work-around for this where it "cheats" by opening additional connection handles where necessary. That's actually a pretty ugly hack that can lead to deadlocks, etc...
