Hi Edward, Alan, I plan to commit the following patch: http://people.freebsd.org/~jlh/racct_munlock.diff This solves the following panic: panic: racct_sub: freeing 301989888 of resource 5, which is more than allocated 73728 for pwsafe (pid 4177) The problem is that the racct code in sys_munlock() trusts too much the user's input. vm_map_unwire_count() now returns how much memory has really been unwired. Any objection? -- Jeremie Le Hen Scientists say the world is made up of Protons, Neutrons and Electrons. They forgot to mention Morons.
