PHP's diskfreespace() function fails due to an error in RH6's glibc, see http://www.progressive-comp.com/Lists/?l=php3-general&m=92870575015735&w=2 I have also seen problems with Samba - related to Red Hat 6's glibc version (which is a pre-release of glibc). I think that an updated set of glibc RPMs (with the _released_ glibc 2.1 - not the pre-release) is an urgent need. Any time frame for that?
I just fixed this in inndf by doing s/f_frsize/f_bsize/. I'm going to coalesce this with the other glibc reports. I can't say when it will be fixed, but Soon is my guess. *** This bug has been marked as a duplicate of 2546 ***
