I have two servers setup exactly the same (for the most 
part.)

I don't know much about linux and this other company put it 
together but both installations have the same version of 
Red Hat on it and I use the same exact commands to install 
apache/PHP on both servers.

This second server processes and works with Sessions 
perfectly fine. NO hitches. The problem is that the server 
is password protected so I cannot give access to my 
tests.I'll see if I can get a non-protected virtual server 
on there for you to see.

It's got to be a server installation thing, I think. What 
could be some issues with an OS installation which could 
cause this problem?

YOU CAN MARK AS SOLVED OR BOGUS (or use this as some way to 
improve the system?)

My sessions are fixed. I compaired the two php.ini files 
from the server that works and the server that didn't work.  
Here's the two.  notice the one difference (trans-id).

Working server:
[Session]
session.save_handler      = files   ; handler used to 
store/retrieve data
session.save_path         = /tmp    ; argument passed to 
save_handler
                                    ; in the case of files, 
this is the
                                    ; path where data files 
are stored
session.use_cookies       = 1       ; whether to use 
cookies
session.name              = PHPSESSID  
                                    ; name of the session
                                    ; is used as cookie 
name
session.auto_start        = 0       ; initialize session on 
request startup
session.cookie_lifetime   = 3600    ; lifetime in seconds 
of cookie
                                    ; or if 0, until 
browser is restarted
session.cookie_path       = /       ; the path the cookie 
is valid for
session.cookie_domain     =         ; the domain the cookie 
is valid for
session.serialize_handler = php     ; handler used to 
serialize data
                                    ; php is the standard 
serializer of PHP
session.gc_probability    = 1       ; percentual 
probability that the 
                                    ; 'garbage collection' 
process is started
                                    ; on every session 
initialization
session.gc_maxlifetime    = 1440    ; after this number of 
seconds, stored
                                    ; data will be seen as 
'garbage' and
                                    ; cleaned up by the gc 
process
session.referer_check     =         ; check HTTP Referer to 
invalidate 
                                    ; externally stored 
URLs containing ids
session.entropy_length    = 0       ; how many bytes to 
read from the file
session.entropy_file      =         ; specified here to 
create the session id
; session.entropy_length    = 16
; session.entropy_file      = /dev/urandom
session.cache_limiter     = nocache ; set to 
{nocache,private,public} to
                                    ; determine HTTP 
caching aspects
session.cache_expire      = 180     ; document expires 
after n minutes

I copied over the config and now it's working fine.

I can't see the difference, but if it works, fine.
