MAXBTLEVEL, Global xxxx reached maximum level

MUPIP Error: This indicates that the global-variable-tree for global xxxx reached the maximum level permissible. Very likely, MUPIP REORG was specified with a fill-factor much less than 100. Small fill-factors can cause REORG to distribute existing GDS-blocks (in order to accommodate the fill-factor requirement), in turn causing block-splits, which might lead to an increase of the tree height.

Action: If MUPIP reorg was specified with a small fill-factor, try higher number (close to 100) to reduce tree-height. Other techniques include increasing GDS-block-size or killing unwanted portions of the tree.
