Hi, there is another ubuntu bug about this:
https://launchpad.net/bugs/1161989 The referenced kernel bug seems to conclude that this is an error with fatrace rather than a kernel bug. Instead, fanotify_init should be called with O_LARGEFILE it seems. A bug for arch linux came to the same conclusion: https://bugs.archlinux.org/task/34520 Attached, find a hack/patch which fixed the problem for me. cheers, josch
Description: works around a limitation on 64bit systems and files larger than 2G If opening a file larger than 2G on a 64bit system, fatrace will quit with "read: Value too large for defined data type". This patch works around this issue until it is fixed elsewhere.
