One critical issue that the LVBS kernel platform suffers from is OOM. Currently, we are trying to avoid this issue in conservative and ad-hoc manners like restricting the number of active userspace instances/sessions (i.e., processes/threads) and the size of buffers for syscalls and inter-world communications. This approach can waste a large portion of secure-world memory block some normal app behaviors.
