I have to say that this is the first time I have heard of someone running multiple gmetads/frontends on the same server although I cannot see why it will cause problems, since you are already using separate XML ports (8651 & 8652) and different locations for frontend docroot. However, I guess to troubleshoot your issue, perhaps what you should do is test whether *one* installation works fine. If it does, then there must be something wrong with the new setup. Let us know how it goes. Cheers, Bernard ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
