Hmm, I do not know why this only happens in DNE, since it is nothing different compared single MDT run. The only reason here, might be in DNE it use 2 OSS (4 OSTs each OSS), in single MDT, it use single OSS with 8 OSTs. I do not know why we only use 1 OSS in single MDT test.

And also discarded pages might be related with memory pressure, but I did not figure out the real reason yet. For now, I will disable this test for DNE.

Patch landed to Master.

The patch was landed to disable sanity.sh test_101a, but the problem was never actually fixed. The bug shouldn't have been closed.
