Somewhere on the internet there’s a mailserver with a larger uptime, I guess?
[root@xxxxxxxx ~]# uname -a Linux xxxxxxxxxxxxxxx 2.6.18-419.el5 #1 SMP Fri Feb 24 22:47:42 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux [root@xxxxxxxx ~]# uptime 09:34:38 up 2290 days, 1:47, ....
I don’t think anyone dares to reboot it …. (this is a server the customer was going to migrate off about 5 years ago …. somehow it’s still in use)
(2290 days is a little over 6 years)
