Hello, It seems that cyrus 2.4.16 packaged for Debian Wheezy does not use msync for mmap'ed files, but only munmap. This is a potential source of trouble with NFS. Also, browsing git repo, appears that git 2.4 branch is using msync now. Is it correct? http://en.wikipedia.org/wiki/Mmap http://nfs.sourceforge.net/ Question D8 and D10 other links http://stackoverflow.com/questions/14626188/mmap-local-v-s-nfs-file-what-happens-when-the-underlying-file-is-replaced-on-di http://git.cyrusimap.org/cyrus-imapd/diff/?id=8220d24e208f5e03ff3dda28e938b66929750f14 http://git.cyrusimap.org/cyrus-imapd/tree/cunit/buf.testc?id=8220d24e208f5e03ff3dda28e938b66929750f14&h=cyrus-imapd-2.4 https://bugzilla.redhat.com/show_bug.cgi?id=151284 https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=152548 http://lists.freebsd.org/pipermail/freebsd-sparc64/2003-May/000146.html old... http://fixunix.com/unix/84153-posix-i-o-nfs-noac-option.html Regards.
