Update to Lion 10.7.4 and Security update 02/2012 upped Ruby load to the ceiling

After updating our home Mac mini server to Lion 10.7.4 and Security update 02/2012, with the machine now just sitting idle, no user logged-in, network cable unplugged, Ruby is generating 96% load on the CPU at all times, with processor temperature running near its limit and fans blowing full-blast.

Switching off the Wiki server cut the load back to normal, Ruby process went behind the curtain, and things appear back to normal, but of course this is no cure, it's just a temporary fix-up.

Any other user is experiencing anything similar?

Any possible solution in form of a next update coming soon, for the graphic-shell-only illiterate users like me?

I'm afraid that I have no answer to your specific Ruby issue. The 10.7.4 update to my mini server has had no problems at all (so far :-}).

However, I'm confused by your reference to Security Update 2012-002, which is intended only for machines running Snow Leopard. I would not be surprised if it caused instability when installed on a Lion system. I would have expected the install process to complain that it could not be added to Lion.

As a rule of thumb, I find that updates are less troublesome when using the Combo updater, rather than the basic point release update.

You may need to back out the update (by restoring from Time Machine or other backup), then re-apply the correct (server-specific) upgrade.

Yesterday I applied the latest Lion Server Update to my Mac Mini Server (not sure about the update's number).

I also experienced the "fans blowing full-blast" symptom for no apparent reason (no heavy apps running - Mac almost idle- and CPU, HDD, Network monitors flatlining). As well as a minor issue on the screen-sharing side: it didn't display the initial grey-background login page, but after I logged in blindly it was fine.

The update did a restart but no power-off, so I thought the issues might occur because the hardware hadn't properly reset (yep, I had to use Windows at work...)

Dunno if that was the cause, but after a shutdown, power-off and restart, the symptoms disappeared. Will see... so far so good.
