See discussion in several distro bug trackers, e.g. BugLink: http://bugs.launchpad.net/bugs/663090 https://issues.rpath.com/browse/RPL-2054 You don't want to raise the default soft limit, since that might break apps that use select(), but it's safe to raise the default hard limit; that way, apps that know they need lots of file descriptors can raise their soft limit without needing root, and without user intervention. Ubuntu is doing this with a kernel change because they have a policy of not changing kernel defaults in userland. While 4096 might not be enough for *all* apps, it seems to be plenty for the apps I've seen lately that are unhappy with 1024.
