Hello Igor: The locker number does indeed continue to grow, in the 500s one time even into the 1000s. My next problem is this, I have it installed 2.1.12 from the tar source, what steps should I take to install the new version? Should I download the source, or is it possible for me to use the rpm on RH8? I saw the readme from the rpms and it said not to install it if you have previously tried to install from source. What should I backup prior to trying to install either the source or the rpm?
