I’ll be rebooting all servers around 3AM for a kernel upgrade. Downtime for any given service will be around ten minutes. The total process should take about 1/2 hour.
Much of the webserver refused to run PHP code randomly today after I compiled in mod_authnz_external. It should not have done this, should not in theory conflict with any of the other apache mods but obviously it did. I will be doing further experimentation to try to nail down the cause. I have had multi-core compiles of Apache blow up before so I may attempt a single core compile and see if that works.
