A QNX Neutrino system consists of a microkernel (proncto) and various processes. Each process runs in its own virtual memory space. The advantage of using virtual memory is that one process can't corrupt another process's memory space. However, each process can have its own memory problems that lead to improper behavior, including crashing or becoming very slow or unresponsive due to excessive memory usage. The IDE provides tools that help you detect and fix these situations.
