@chenyou-intel The problem was caused by incorrect memory tier sizes that were used to determine per tier pool sizes. I submitted a fix and new regression tests for review (#76). If you want to try the fixed code before the promotion to develop is complete, please use this branch: https://github.com/pmem/CacheLib/tree/issue75.
