Claus Ibsen commented on CAMEL-3125:
------------------------------------
Read chapter 4 in the Camel in Action book which tells you background about
error handling and where it _lives_ / _applies_.
The rule of thumb is the Camel error handling works with messages, eg when an
Exchange has been created and handed from the component to Camel.
Before that its per component specific how they deal with their errors. That is
component specific.
> When the fetching of a feed causes, polling continues endlessly, flooding the
> logs and creating unwanted network load.

> Key: CAMEL-3125
> URL: https://issues.apache.org/activemq/browse/CAMEL-3125
> Project: Apache Camel
> Issue Type: Wish
> Components: camel-rss
> Affects Versions: 2.4.0
> Environment: ubuntu 10.4
> java 6
> Reporter: Ernst Bunders
> Assignee: Claus Ibsen
> Fix For: 2.5.0
>
> Attachments: LimitingPollingConsumerPollStrategy.java
>
>
> The problem is with the default implementation of
> org.apache.camel.spi.PollingConsumerPollStrategy:
> org.apache.camel.impl.DefaultPollingConsumerPollStrategy
> When an error occurs rollback() is called, and this method just logs the
> error and returns false, which means the polling will not be retried for that
> execution of the run() method.
> This means it will be retried after the delay.
> I created an implementation that suspends the Consumer, which seems like
> acceptable default behavior. It also allows for extension and adding some
> hooks for custom stuff. In order for that to be useful it should be made
> easier to set your own PollingConsumerPollStrategy implementation.
