File locks and the IOException "Object is to large to process."

[Dan <nc1906@xxxxxxxxx>]

Hi all.

I was wondering if anybody has seen this problem. 
When trying to lock a file in java 1.4 on the As400,
an IOException : ?Object is to large to process. Lock
Failed.? is thrown.  The things is the file is only 10
characters long.  Is there a good work around for this
without changing the code?  Has anybody ever seen this
exception in the case of a small file?

Here is the code:
try{
FileChannel channel = null;
RandomAccessFile raf = null;
raf = new RandomAccessFile(file,"rw");
channel = raf.getChannel();

// Try acquiring the lock without blocking. This
method returns
// null or throws an exception if the file is already
locked.
if(channel.tryLock() == null){
retval = false;
logger.error("File in use by another object or
process: "+file.getAbsolutePath());     
}
channel.close();
raf.close();

}catch(Exception e){
        e.printStacktrace();
retval = false;
logger.error("File in use by another object or
process: "+file.getAbsolutePath());
}

Thanks!

Dan
