Ah.

I'm not sure why it hangs, but there is a problem with the ct_cancel()
call in some cases. DBD::Sybase fetches the @@version from the server
during the DBI connect() call to enable/disable certain behaviors, and at
the end of that call executes a $sth->finish, which maps to ct_cancel()
by default.

If you change your connect() call and add syb_flush_finish=>1 in the
attributes you should be fine:

$dbh = DBI->connect("DBI:Sybase:$server",
                    $username,$pw,{RaiseError => 1, syb_flush_finish=>1});
