 One difference is that the fallback behavior for batch listeners (when an exception other than a `BatchListenerFailedException` is thrown) is the equivalent of the <<retrying-batch-eh>>.
 
 IMPORTANT: Starting with version 2.9, the `DefaultErrorHandler` can be configured to provide the same semantics as seeking the unprocessed record offsets as discussed below, but without actually seeking.
-Instead, the records are retained by the listener container and resubmitted to the listener after the error handler exits (and after performing a single paused `poll()`, to keep the consumer alive).
+Instead, the records are retained by the listener container and resubmitted to the listener after the error handler exits (and after performing a single paused `poll()`, to keep the consumer alive; if <<retry-topic>> or a `ContainerPausingBackOffHandler` are being used, the pause may extend over multiple polls).
 The error handler returns a result to the container that indicates whether the current failing record can be resubmitted, or if it was recovered and then it will not be sent to the listener again.
 To enable this mode, set the property `seekAfterError` to `false`.
