Hi Johnny, Thanks for the explanation. yes I do understand that critical patches needs to be applied for any OS. But in this case it is not a stand alone machine, it is a cluster suite and OS was not installed separately. I would have definitely upgraded the system if this was stand alone box. If I remember correctly, long back I was suggested not to upgrade cluster suite due to various reasons. Though I will check on this and see if its upgradable. If it is, I will try it out.

I know its quite old but I cant update as its running with cluster suite and its a production unit. Moreover its not feasible to upgrade as I have hundreds for apps and data lying on the system.

Staying on any version of CentOS except the latest in a branch is not safe. CentOS-5.10 is CentOS-5.4 with just bugfix and security updates. CentOS-5 is safe, CentOS-5.10 is safe. CentOS-5.4 is unsafe. For the record, there are more than 300 security updates released, dozens of them rated as Critical after 5.4 in the CentOS-5 tree (currently 5.10). Critical means remotely exploitable. Updates within a branch (that is, updates that stay on the CentOS-5 family in this case) SHOULD work and not break things. Obviously bugs happen and sometimes things do not work ... that should be the exception, not the rule. It is imperative that people install security updates, otherwise it is not a question of if, but when their machines will be exploited. > > > > On Thursday, 27 March 2014 1:30 PM, Alexander Dalloz <ad+lists at uni-x.org> wrote: > > Am 27.03.2014 06:22, schrieb Hersh Parikh: >> Hi Frank, >> >> Thanks for quick response.
