Question

With the following file configuration, the application consistently provides a WARN issue. Please see below for an example of the logs.

WARN  2014-04-15 18:46:59,824 [Finalizer] org.mule.transport.file.ReceiverFileInputStream: Failed to move file from /file/file/processing/file.file to /file/file/archive/file.file

The connectors are setup in the following way:

<file:connector name="InputFileConnector" doc:name="File Connector" workDirectory="${Processing_Path}" 
            workFileNamePattern="#[message.outboundProperties['originalFilename']]" moveToDirectory="${Archive_Path}" 
            moveToPattern="#[message.outboundProperties['originalFilename']]"
            streaming="true" autoDelete="false" validateConnections="true" fileAge="${FileAge}"/>

Inbound-endpoint Configuration:

<file:inbound-endpoint responseTimeout="10000" doc:name="File" path="${Inbound_Path}" pollingFrequency="${PollingFrequency}" connector-ref="InputFileConnector">
            <!-- Add filename-regex-filter to insure files are there to kick off the process -->
            <file:filename-regex-filter pattern="SAMPLE\d+\.FILE" caseSensitive="true"/>
        </file:inbound-endpoint>

I am looking for any insights or suggestions on what is causing this WARN issue in Mule.

Update Change streaming attribute to false, resolves the WARN issue.

Was it helpful?

Solution

Mule has some issues with streaming file endpoints, so you could try your app with streaming="false" in the connector. I don't know exactly what is going on with the Mule file streaming, but I guess it could be something like an open file handle that produces an exception when the file is removed from the processing list.
