In the extremely unlikely event that the process consuming all the memory has a pid less than 48, the system will hang. This is extremely unlikely because when the pids wrap at 32767, then wrap back to 100, so usually only processes that were started at system startup time will have pids < 100. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
