Please forgive my long email I was not sure if the mailing list
supported attachments, since when I go to the archive I do not see any
attachments.
I am sure I am doing something wrong, but I sure can not figure out what
it is.
First off I built the latest tagged tree I could find JCS_1_2_6_5 and
then built the project using Maven 1.0.2.
I then created my own version of the Book example to see how well the
cache system performed using a remote cache.
Here is my ccf file:

Note that the rmi cache service at the top only appears on the remote
server side.

When I run the remote server by itself the CPU utilization is low. When
I bring up a client and put one thing in the cache, the client cpu goes
to 30% and the server is at 60% and they do not change.
Also when I run the server script like:
./startRemoteCache.sh /remote.cache.ccf 11101 I get port already in
use. So I started up the rmiregisrty on 11102.
stdout of the server side:

If one client performs a cache update, the second client sees it Yeah!!
But if both perform updates, sometimes the reads get the latest value
from the cache, and sometimes the cache returns an older value??? This
does not make any sense to me.
Anyone have any idea what I might be doing wrong?
Thanks for any help,
Bill Eme
