The minimum of 1048576 was set early in the life of the Classic products. The newer versions need a larger size for MESSAGEPOOLSIZE.
Change the value of MESSAGEPOOLSIZE to a value of 16777216 or greater. APAR PM67433 for V9.5 Classic products and APAR PM69239 for V10 Classic products have changed the minimum for MESSAGEPOOLSIZE to 16777216 and will produce an error if MESSAGEPOOLSIZE is set to a value lower that the minimum.
