The following information is only valid if you DO NOT use avfs!

There is a problem in the configure test for checking large file
support (LFS) (files larger than 2 GB). For some systems, mainly
RedHat 7 but perhaps other, the test will deactivate the LFS code
although the system supports it.  This is not a big problem for Worker
but if you want or need to access these large files, you probably want
to enable it by running the configure script with an additional C flag:

  CPPFLAGS="-D_FILE_OFFSET_BITS=64" ./configure

Nowadays this shouldn't be a problem anymore. Just check the output of
the configure script at the end, it will tell you whether large file
support is enabled or not.
