File Consumer Stops Working

[carloc <ca...@yahoo.com>]

Hi everyone,

I'm using camel 1.4.0. We have it deployed in a production environment in
which it runs in a 24x7 scenario.
Problem is every now and then camel suddenly stops working and stops
consuming file. Now I am not sure if this is a problem of the file consumer
stopping, or if the camel context itself stopped working.

 From what I see it is a background thread that is launched. An outofmemory
occurrs when it stops working.
However the instance itself doesn't stop. I don't know if it is in anyway
related to the noop array list that is not cleared up properly. 

Is there a way to monitor camel scheduled consumers so that I can be
notified it stops for some reason?



I'm not sure what can cause it to stop working all of a sudden.

The File component in Camel 1.4 or older has unfortunately a memory
issue if you consume many files.
There are unfortunately no workaround, besides than restarting Camel.

We have fixed this in the next release of Camel = 1.6 (named 1.5.1 in JIRA)
https://issues.apache.org/activemq/browse/CAMEL-1138


If you need a stable release with this bugfix you can try out the FUSE
releases of Apache Camel:
http://fusesource.com/

The maven repo is at:
http://repo.fusesource.com/maven2/

And its basically just to use a different version number.
1.4.0 => 1.5.3.0-fuse




We are in the transition of moving Apahce Camel as a top level project
at Apache so we cant release Apahce Camel 1.6 until this transition is
complete.
