I am getting this exception when trying to download a file 

Caused by: java.io.FileNotFoundException: /repository/PWWVFSYWDW0STLHYVEEKHMYBXZTTETGROCQ4FGdsadadaXR1407709207964905350810526.jpg (File too large)
at java.io.FileOutputStream.open(Native Method)

It is clear that file the exists. In addition to that, the same program works properly on my PC, but there is a problem with the server, which is Unix

Any ideas what might be causing this?

I think that this is an obscure error that is actually coming from the OS level or the JVM's native code implementation. The message "File too large" is the error message that you would get if the perror C library method was used to render the EFBIG error number.

Now ordinarily, this should not happen. According to the UNIX / Linux manual entries, the various open library calls should not fail with EFBIG.

However, I have seen various error reports that imply that fopen (etcetera) can fail like that on some file systems, and/or when the a C / C++ program has been built with 64bit file size support disabled.

So what does this mean?

It is not clear, but I suspect that it means that you are either:

  • using a flaky implementation of Java,

  • running a flaky release of UNIX / Linux, or

  • you are trying to use some type of file system that is not well supported by your server's OS. (Might it be on a FUSE file system?)
