Indeed. The complaint is about the sample configuration size that needs to be larger, but often you cannot really do so without making the MONDCSS larger. The sample provided by z/VM is too small for most installations. There is no penalty for making it a bit too large, and we find that 64M works for most folks. The size of the sample configuration area in the MONDCSS is set when the monitor is started (the default of 241 pages is too small for many). My rough estimate is one page for every 10 devices defined. Your performance monitor will tell you how much is really being used.
