David, Take a look at Note 19332.1, which explains the error and what to do next.
In short, the essence of the note is: The error comes if the time waited is mor than the value of the distributed_lock_timeout parameter. Even if you do a select from the remote database, it acquires a TX lock and that can wait. Increase the value of the timeout or, just use an exception handler on the commit statement to retry. HTH.
