On Windows 2000 i've encountered a 2GB limit on the size of a ZODB file. Is there such a limit on Linux (vanilla Redhat 8, out of the box), and if so, what is that limit? If I'm not wrong, that was a problem with the c library of the old kernels. The new kernels include large file support; however, you have also to compile python to support it. Search the archives or zope.org to see how this is done. There is a couple of how-tos.

I've tested files bigger than 2 Gb on RedHat 7.3 and the latest kernel and it works, so I guess it should work for 8.0 too. Regards, Josef
