Running Oracle 11.2.0.4. Doing a migration from Windows to Linux. We are noticing considerably larger pga size for the m000 process. Anyone know of a memory leak or is this expected from changing platforms. We are using Hugepages in Linux and not in Windows. In Windows the PGA for M000 is around 30M and on our Linux instance about 170 M - a considerable difference.
