So I am currently running ZCS Professional Edition on Ubuntu 8.04 LTS in an ESX environment. I keep running into an issue where after a week or so one of the java processes starts pegging the CPU. It is a single server deployment and I am looking to try and optimize the stability and performance.
I was thinking of migrating to a multi-server deployment to spread the load out and also help trace down which component is causing the headache's. I was going to just use the same Ubuntu distro since it is the standard in our environment but then figured I should maybe investigate other distro options.
So my question is, are some distro's more stable with zimbra then others? If I go with SUSE, RedHat or CentOS am I going to see better results running ZCO? If it doesn't really matter I will probably stick with ubuntu but we do have a few CentOS 5 boxes in the environment I have to support anyway so I wouldn't be against RH or CentOS.
What do you guys think?
