Could someone please help. It is rare for a 'yum update' to disturb already working applications. It is possible of course, but the point of 'enterprise' distributions is that a lot of care is taken to not break things (i.e. make changes that aren't backwards compatible) within a major release version. Not sure if it is necessary but there were some quirks in the updates along the way that might make it a good idea to: yum update glibc\* rpm\* yum\* python\* before doing a full 'yum update'. -- Les Mikesell lesmikesell at gmail.com
