Thanks John. I just looked up the Horde website. Will download and set it up. Meanwhile, any more details, besides the install, that you think would help set this up in least amount of time would be helpful, like, how to crank the incoming user rate etc. Such help will enable us to focus more on the file system rather than setting up the the application load.

Thanks for helping out.

I suppose.  It's Horde, a PHP-based groupware suite.  I've got two 
Apache nodes load-balanced using glusterfs as their php sessions store 
plus shared data (temp files, misc app data) with the sessions store 
being the hard-hit service.  When I crank up the incoming user rate, 
(causing new sessions to be created and then read), things get wonky as 
explained before.
