I am not against 64-bits (we use it for many, many years using Solaris) but what concerns me is the stability of 64-bit Linux. Can you share your experience regarding stability of 32-bit and 64-bit CentOS ? Does anybody use 64-bit CentOS in production (web applications) environment ? > > Regards > przemol > > We had just started retooling Web servers to 64bit (overcoming some 32bit limitations in 3rd-party stuff). We had run 64bit on almost everything else before (few thousand production systems). There was no issue of stability in 64-vs-32 bit. For the Web servers, we found it might actually be more stable in the environment compared to 32bit, due to differences in memory management in the 64bit environment. Of course, you should test in your circumstance - but I (and others here) have positive experiences. -Alan
