I know that SQL server can return multiple datasets. Is it possible that one of your proces is returning an additional dataset that you're not reading? You could check that by preceding the failing statement with a fetch loop, printing out any data you find.

In any case, you might want to read the docs on the Active method to test whether the the statement handle is still active and finish to terminate the statement if so.

Caveat: I've not tried this in the last few years, so my recollections could be a bit fuzzy.

Update: Fixed links to cpan. (I used http://search.cpan.org/~timb/DBI-1.622/DBI.pm#Active, but I don't know if that's the best way to do it. I didn't get anything useful when I tried cpan://DBI#Active.
