Subject Re: ManifoldCF two server setup

Hi Shashank,

You can have multiple servers running against the same database, BUT if you
do so, they must be individually configured to have their own IDs, and they
must share locks and by extension, must use the same zookeeper.
See multiprocess-zk-example in the binary distribution.
