Java.io.IOException: invalid argument

Question

I have a web application running in cluster mode with a load balancer. It consists of two cats (T1 and T2), addressing only one database. T2 - nfs installed on T1. This is the only problem between both nodes.

I have a java method generating some files. If the request runs on T1, there is no problem, but if the request runs on node 2, I get an exception as follows:

java.io.IOException: Invalid argument
        at java.io.FileOutputStream.close0(Native Method)
        at java.io.FileOutputStream.close(FileOutputStream.java:279)

The corresponding code is as follows:

for (int i = 0; i < dataFileList.size(); i++) {
    outputFileName = outputFolder + fileNameList.get(i);
    FileOutputStream fileOut = new FileOutputStream(outputFileName);                        
    fileOut.write(dataFileList.get(i), 0, dataFileList.get(i).length);
    fileOut.flush();
    fileOut.close();
}

An exception appears in Out.close ()

Any clues?

Answer 1

Finally, I found the reason. At first I notice that this exception does NOT always come at the same point.

  java.io.IOException:        java.io.FileOutputStream.close0 ( )        java.io.FileOutputStream.close(FileOutputStream.java:279)                                   ^^^^^
