I only reboot on kernel upgrades, that is usually more often than 6 months. But if you don't need to reboot for that reason, I would not reboot at all. > > btw this uptime really confirms me how stable Centos 4.x really is > and so I wonder how long some people's uptimes on the list are ;) > > rmc You should consider upgrading your kernels when security updates come out ... just to be safe. Especially for machines touching the internet. I usually upgrade my kernels because I like to use LVM snapshots for backups and that has only really started working semi-well since 4.3 and even better in 4.4 ... so most of my machines get rebooted every new kernel, which is at least 2-3 times a year (sometimes more often). That being said, I do have a non internet facing machine that has not been rebooted since it was installed with CentOS-4.0 on it one March 1, 2005. It is an internal router on my employer's infrastructure, and has been up for almost 2 years (and was installed on the day before CentOS-4 was officially released). Thanks, Johnny Hughes
