We've outgrown our single server we were using for our forums. Our site now uses 4 web servers and 1 Database server. We found that when we run UBB 6.5 on a load balanced server for the most part things are ok. All posts are contained in the database. But when we do things like edit templates or users attach a file it's luck of the draw if you are on the primary server or not. If you are not on the primary server any changes get wiped.
We will be upgrading soon to the latest version of UBB. But does the latest version have any features for working across multiple servers?
We have a work around in place right now. We did an NFS share to our database server so that all of the files are on one share and each web server thinks they are local. This works for now. But as we grow this will no longer be a solution.
I'd be interested to know of the latest version addresses these issues or is anyone has any good workarounds.
