The suggested activity is an update (you stay with the same OS, libs etc.) and this will not break any compatibility with an already running 3rd party software. I mean if someone is scared about the "production" system, will it change a broken harddisk if it is faulty? 5.4 is faulty - it is an inherent attribute of software that mistakes are found and corrected. So my suggestion is; reboot your system to check to functionality of all services after this. then update your system with yum update rpm* glibc yum*; yum update to your original question: you can not use a more recent glibc version. it is not just an optional piece of software that can be altered, it is the main/core part of an OS ... -- LF
