Changes in this Release
Unable to startup with full SPC size on AIX
Due to compiler optimization, it was not possible to startup with the largest possible shared page cache size on AIX. With 32-bit GemStone on AIX, in versions before v6.7.2 it was possible to start a 2.99GB cache; in v6.7.2 the possible SPC size was limited to 2GB on AIX. (#49693)
