Re: [K12OSN] (SOLVED) 4GB memory limit?

Oh, looking at the title, I should add I never did solve the actual 4GB part -- but those two extra GB RAM chips in my servers will just have to keep each other company for a while. 4GB is working, so for now, I'm happy. :)

This morning, things are going quite swimmingly. Here are the things I've changed, I'm not sure if one or several things were the "Magic Bullet." But things are working nicely now.

* Updated Firefox to the latest tar.gz from mozilla. Not the beta of v3, but the latest stable version 2. I just put it in /usr/ local and symlinked /usr/bin/firefox to that.

* Tweaked the snot out of my NFS server. We had chaos yesterday morning, on more than just the thin clients, because our ISP switched their DNS server address. I switched all our other servers, but failed to switch over the file server, and as it hung on DNS, it wouldn't allow NFS clients to connect. This messed up both the thin clients, AND the OSX machines. I also upped the number of NFS daemons running from 8 to 16, and increased the memory sizes (via the nfs performance tweaking site).

* I also removed the pretty background image from KDM. I doubt it had much to do with the problem, but it seemed superfluous, so I switched it to a patterned background.

So far, things are working great. Firefox loads fairly quickly, and everything else works about like I'd expect it to. There are a few straggling thin clients with goofy hardware that I need to tweak in my lts.conf, but other than that, I think we're all set.

Also, I didn't upgrade (cross grade?) to 5EL, because quite frankly, I wanted to sleep a little last night. :) As long as FC6 gets us through the school year, I'm a happy camper.

Thanks for all the help!
