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.
