We ran into this error a lot in the past. To the point of hundreds a
day sometimes. Here's an article that has a possible solution:

Our DBAs spent weeks talking to Oracle about this three years ago when
we first started seeing it, and Oracle mentioned the same setting. The
downside is that it potentially slows down some queries. We never
ended up trying it, though. Ultimately our problem was mostly solved
when we acquired new database hardware that wasn't completely
overloaded by Sakai. We still see the error from time to time but it
went from a daily occurrence down to a rare thing. Only on seven days
in the past year have we seen the error at all, and the total
incidences this year is fewer than a single day often saw on the old
