Subject [jira] [Commented] (CAMEL-4105) Thread controlling FTP Polling Process dies
Date Wed, 15 Jun 2011 15:47:47 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-4105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13049825#comment-13049825

Claus Ibsen commented on CAMEL-4105:
------------------------------------

I can see you use a FuseSource product. If you are a FuseSource subscriber then I suggest
to use that channel to get help with your issue. They can provide you with a solution for
your current version so you dont have to do a upgrade.

That said I am adding more logic in the ScheduledPollConsumer so we do a full try .. catch(Error
e) to catch any kind of errors thrown to avoid the thread from dying. This may possible cause
the JDK scheduled thread pool to fail scheduling the task. 

Also I am adding a runLoggingLevel option you can use to enable to configure a logging level
that logs: START, COMPLETE on the scheduled task. Then that may help us/you to see when it
stops logging that. Likewise there is a ERROR that logs all thrown error from the thread.

> I have several threads each polling a different FTP Remote folder location.  This works
fine for a couple of weeks then one or more FTP Threads die (disappear).  I'm going to attach
a snippet from my log file below.  Notice that normally the connection to the FTP site does
not exists.  The connection is then made and the folders are checked then the FTP process
disconnects.  Some of the folders are on the same remote FTP site and I don't know if that
causes a problem or not.
> The first time I notice that the thread is dead is when the code starts checking the
FTP threads to see if they are connected and I notices that not all of the thread are listed.
