puuh ... long time ago ... let's try think using KSM & page-locking led to more stuff locked than actually intended/expected (all memory used by ksm iirc) which subsequently drove the system into real trouble having to do heavy swapping on the little memory left. In your case without swapping it is hard to guess what would actually happen rather than oom which is obviously not happening. I would expect this issue anyway to be solved meanwhile but anyway ... Sorry for the degradation of my biological data-store. There should be something on disk somewhere but unfortunately I have no access atm.
