335544327=invalid request handle

It, most likely, happens only then, when you have prepared some statement,
used it, then some "fatal" error happened, JayBird recycled the connection
(at this point handle is no longer valid) and your application tries to
reuse that prepared statement. This error means only that your prepared
statement is no longer valid and should be re-prepared.
