This issue is currently being hit by some enterprise sized daemons (lots of open fds). The biggest issue is that almost every use of select is wrong, so fixing them all in a timely manner is rather impractical. Some projects like Samba have already moved to poll(), but they're now hitting fd issues in various libraries. I do agree that this is a library bug, but I think given the situation, it could make sense to add a fix for this to glibc to prevent buggy select use from overwriting arbitrary bits in memory. It's obvious that most projects don't use select() properly, even though its correct use is documented in the man pages. Thanks. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
